Hell -exothermic or endothermic?


The following is an actual question given on a University of Washington chemistry mid term.

The answer by one student was so 'profound' that the professor shared it with colleagues, via the Internet, which is, of course, why we now have the pleasure of enjoying it as well :

Question: Is Hell exothermic (gives off heat) or endothermic (absorbs heat)?

Most of the students wrote proofs of their beliefs using Boyle's Law (gas cools when it expands and heats when it is compressed) or some variant.

One student, however, wrote the following:

First, we need to know how the mass of Hell is changing in time. So we need to know the rate at which souls are moving into Hell and the rate at which they are leaving. I think that we can safely assume that once a soul gets to Hell, it will not leave. Therefore, no souls are leaving. As for how many souls are entering Hell, let's look at the different religions that exist in the world today.

Most of these religions state that if you are not a member of their religion, you will go to Hell. Since there is more than one of these religions and since people do not belong to more than one religion, we can project that all souls go to Hell. With birth and death rates as they are, we can expect the number of souls in Hell to increase exponentially. Now, we look at the rate of change of the volume in Hell because Boyle's Law states that in order for the temperature and pressure in Hell to stay the same, the volume of Hell has to expand proportionately as souls are added.

This gives two possibilities:

1. If Hell is expanding at a slower rate than the rate at which souls enter Hell, then the temperature and pressure in Hell will increase until all Hell breaks loose.

2. If Hell is expanding at a rate faster than the increase of souls in Hell,then the temperature and pressure will drop until Hell freezes over.

So which is it?

If we accept the postulate given to me by Teresa during my Freshman year that, 'It will be a cold day in Hell before I sleep with you,' and take into account the fact that I slept with her last night, then number two must be true, and thus I am sure that Hell is exothermic and has already frozen over. The corollary of this theory is that since Hell has frozen over, it follows that it is not accepting any more souls and is therefore, extinct......leaving only Heaven, thereby proving the existence of a divine being which explains why, last night, Teresa kept shouting 'Oh my God.'

What may happen in 2012 that wipes out the world?

Although it seems just odd and highly improbable that the world will suddenly wipe off the face of Earth . But the hype around it is really immense. I looked up some ways which can end the world in a jiffy.Take a look and see if you agree.
  • Asteroid Impact

This is the first thing that comes to mind.They wiped out dinosaurs and can do it again. Rocks hit the Earth almost every day but none are big enough to cause any trouble.A huge one can still find its way to Earth although the chances are about 1 in 700,000. 

One more thing, since we are not dinosaurs, the chances are that we'll see one of them coming and destroy it or deflect it off path.
  • Supernova 

A supernova  is a stellar explosion. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months. During this short interval, a supernova can radiate as much energy as the Sun could emit over its entire life span. The explosion expels much or all of a star's material at a velocity of up to 30,000 km/s (a tenth the speed of light), driving a shock wave into the surrounding interstellar medium. This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant.

This surely is something capable of the task at hand but again it has odds of about 1 in 10,000,000 . 
  • Gamma-ray Burst
Gamma-ray Burst

Gamma-ray bursts (GRBs) are flashes of gamma rays associated with extremely energetic explosions in distant galaxies. They are the most luminous electromagnetic events occurring in the universe. Bursts can last from milliseconds to nearly an hour, although a typical burst lasts a few seconds. The initial burst is usually followed by a longer-lived "afterglow" emitting at longer wavelengths.

Just a fact-Gamma rays are capable of penetrating a 30 cm thick sheet of metal.So, you can understand the danger.
Odds- 1 in 14,000,000.
  • Solar Flare
Solar Flare

A solar flare is a large explosion in the Sun's atmosphere that can release as much as 6 × 1025 joules of energy.

Odds- Almost nil
  • Death Of Sun
Death of Sun
The Sun does not have enough mass to explode as a supernova. Instead, in about 5 billion years, it will enter a red giant phase, its outer layers expanding as the hydrogen fuel in the core is consumed and the core contracts and heats up. Helium fusion will begin when the core temperature reaches around 100 million kelvins and will produce carbon, entering the asymptotic giant branch phase.
When this happens, Earth would be toasted but do we need to start worrying now?It isn't going anywhere for billions of years.
  • Black Hole
Black Hole
A black hole is a region of space from which nothing, including light, can escape. So what chance does our poor Earth stand.
But odds of one coming close enough are about 1 in 1,000,000,000,000.
  • Death of Universe
Earth is surely in danger if this happens, if all matter decays. Do I need to discuss the odds of this happening any time soon.
  • Alien Attack

The odds of this happening are probably better than some of the things discussed above. If aliens decide to attack us and give us severe nose bleeds we are in for a hard time.

Amazing Extinct Animals

All of us have heard about the various species under threat of extinction and loads of efforts are being made to help them survive. But many such species have already disappeared off the face of Earth...they are extinct.
Here are some of those amazing creatures that won't be seen again:

  • Tyrannosaurus Rex (Extinct about 65 million years ago)

T. Rex is surely the first that comes to mind when you think of 'extinct animals'.
Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen, measured 12.8 metres (42 ft) long, and was 4.0 metres (13 ft) tall at the hips. Mass estimates have varied widely over the years, from more than 7.2 metric tons (7.9 short tons), to less than 4.5 metric tons (5.0 short tons), with most modern estimates ranging between 5.4 and 6.8 metric tons (6.0 and 7.5 short tons).

  • Thylacine (extinct since 1936)

The Thylacine (Greek for "dog-headed pouched one") was the largest known carnivorous marsupial of modern times. It is commonly known as the Tasmanian Tiger (because of its striped back), the Tasmanian Wolf, and colloquially the Tassie (or TazzyTiger or simply the Tiger. Native to continental Australia, Tasmania and New Guinea, it is thought to have become extinct in the twentieth century around 1936.
  • Irish Elk (Extinct  about 7,700 years ago)

The Irish Elk or Giant Deer (Megaloceros giganteus), was a species of Megaloceros and one of the largest deer that ever lived. Its range extended acrossEurasia, from Ireland to east of Lake Baikal, during the Late Pleistocene. The latest known remains of the species have been carbon dated to about 7,700 years ago.Although large numbers of skeletons have been found in Irish bogs, its common name, Irish Elk, is misleading as the animal was not exclusively Irish, and neither was it closely related to either of the living species currently called elk; for this reason, the name "Giant Deer" is preferred in more recent publications.
  • Quagga (Extinct since 1883)

The quagga (Equus quagga quagga) is an extinct subspecies of the Plains zebrawhich was once found in great numbers in South Africa's Cape Province and the southern part of the Orange Free State. It was distinguished from other zebras by having the usual vivid marks on the front part of the body only. In the mid-section, the stripes faded and the dark, inter-stripe spaces became wider, and the rear parts were a plain brown. The name comes from a Khoikhoi word for zebra and is onomatopoeic, being said to resemble the quagga's call. The only quagga to have ever been photographed alive was a mare at the Zoological Society of London's Zoo in Regent's Park in 1870.
  • Megatherium (Extinct about 11,000 years ago)

Unlike its living relatives, the tree slothsMegatherium was one of the largest mammals to walk the Earth, weighing five tons, about as much as an African bull elephant. Although it was primarily a quadruped, its footprints show that it was capable of assuming a bipedal stance. When it stood on its hind legs, it was about twice the height of an elephant, or about twenty feet tall. This sloth, like a modern anteater, walked on the sides of its feet because its claws prevented it from putting them flat on the ground. Megatherium species were members of the abundant Pleistocene megafauna, large mammals that lived during the Pleistocene epoch.
  • Woolly Mammoths (Extinct 11,000 years ago)

Woolly mammoths were elephant like animals with tusks as long as 3.5 m long.Unlike most other prehistoric animals, their remains are often not literally fossilized - that is, turned into stone - but rather are preserved in their organic state. This is due in part to the frozen climate of their habitats, and also to their massive size. Woolly mammoths are therefore among the best-understood prehistoric vertebrates known to science in terms of anatomy.

  • Dodo (Extinct since late 17th century)

The dodo (Raphus cucullatus) was a flightless bird endemic to the Indian Ocean island of Mauritius. Related to pigeons and doves, it stood about a meter (3 feet) tall, weighing about 20 kilograms (44 lb), living on fruit and nesting on the ground.
The dodo has been extinct since the mid-to-late 17th century.It is commonly used as the archetype of an extinct species because its extinction occurred during recorded human history, and was directly attributable to human activity.
The phrase "dead as a dodo" means undoubtedly and unquestionably dead, whilst the phrase "to go the way of the dodo" means to become extinct or obsolete, to fall out of common usage or practice, or to become a thing of the past.

  • Megalodon (Extinct 1.6 million years ago)

The megalodon  was a giant shark that lived in prehistoric times during the late Oligocene epoch and Neogene period, approximately 25 to 1.5 million years ago, and was a super-predator.
It was by far the largest and most powerful fish of its time and one of the biggest hypercarnivorous predators ever known with maximum size theorized to be around 20.3 metres (67 ft) in length and 103 metric tons (114 short tons) in weight. From scrutiny of its remains, scientists conclude that C. megalodonbelongs to the order Lamniformes but its genus is disputed. Fossil evidence has revealed that C. megalodon had cosmopolitan distribution and fed upon large marine animals.

  • Steller's Sea Cow (Extinct since 1768)

Steller's sea cow (Hydrodamalis gigas) is a large extinct sirenian mammal. Formerly abundant throughout the North Pacific, its range was limited to a single, isolated population on the uninhabited Commander Islands by 1741 when it was first described by Georg Wilhelm Steller, chief naturalist on an expedition led by explorer Vitus Bering. Within 27 years of discovery by Europeans, the slow moving and easily captured Steller's sea cow was hunted to extinction.

Mistakes aren't bad ,not if they lead to new discoveries...are they?

Not all mistakes are bad.Some mistakes, some accidents can get you more than you ever expected. Such mistakes occur in the scientific world quite frequently.Listed here are some of such discoveries and inventions that were a result of the mistakes that worked.

  • Vulcanized Rubber:

The rubber in its original form is practically useless being brittle and stiff when cold and sticky when hot.Charles Goodyear had been trying to make it better for several years.But it actually happened by mistake.He brushed  his hands off that had the 'useless' rubber and some sulphur sticking on them onto a hot stove.He noticed that the rubber formed into some kind of gum and  left it out in the cold nailed to his door. He was astonished to find a perfectly elastic substance there by the morning.

  • X-Rays

In the nineteenth century, the penetrating rays emitted when electrons hit metal were a matter of interest for many.One such guy was Wilhelm Röntgen.One day he was trying to see the effect they had on objects that came in their way .But he was surprised when he saw the bones of his own hand being projected on the wall.This process led to the the discovery of X-Rays as we know them today. 
  • Penicillin

One day in 1928, Alexander Fleming didn't clean up his workstation before leaving.When he returned he found some strange fungus growing on some of his cultures but he was much more surprised when he saw that the bacteria didn't thrive anywhere near it.
Penicillin is still the most widely used antibiotics.
  • Artificial Sweeteners

Not washing hands before eating isn't bad specially if they taste sweet.Thats what the scientists who forgot to wash their hands after working with chemicals like aspartame, saccharin, cyclamate found out.Now wasn't that a sweet mistake.
  • Microwave Oven

The microwave was a result of things getting hot in Percy Spencer's pants, melting the candy bar in his pocket when he came close to a magnetron.
  • Pace Maker

This life saving device was discovered by Greatbatch when he was trying to make a circuit to record the heart sounds. By mistake he used a 1 mega ohm resistor in place of an intended 10,000 ohm one.The resultant circuit pulsed for 1.8 milli-second ,then stopped for a second and then pulsed again giving a perfect heartbeat.
  • Teflon

Roy Plunkett ,in an effort to make a new CFC planned to use a gas called TFE.In order to preserve the gas till the time of use, he cooled it and pressured it into canisters.But when the time of opening the canisters came, the gas was gone. Frustrated, he shook the canisters and out came some white flakes which later formed into the teflon we know today.
  • Radioactivity

Becquerel back in 1896 ran a series of experiments to see if all fluorescent elements emitted X rays in the sun.But the problem was that it was winter time and the sun refused to show up .Becquerel kept his apparatus in a drawer wrapped up in a paper for the meantime.When the sun finally showed itself ,Becquerel found that the uranium rock had left some imprints on the photographic plate even without being exposed to the sun.He studied this with the Curie couple to discover radioactivity.
