# Question: Why Can’T Temperature Go Below Absolute Zero?

## Why is absolute zero only a theoretical temperature?

The laws of thermodynamics indicate that absolute zero cannot be reached using only thermodynamic means, because the temperature of the substance being cooled approaches the temperature of the cooling agent asymptotically, and a system at absolute zero still possesses quantum mechanical zero-point energy, the energy of ….

## Is there an absolute hot?

Absolute hot is a theoretical upper limit to the thermodynamic temperature scale, conceived as an opposite to absolute zero.

## What is the hottest thing in the universe?

A CERN experiment at the Large Hadron Collider created the highest recorded temperature ever when it reached 9.9 trillion degrees Fahrenheit. The experiment was meant to make a primordial goop called a quark–gluon plasma behave like a frictionless fluid. That’s more than 366,000 times hotter than the center of the Sun.

## How fast would you die in absolute zero?

Depending on your current body temperature and structure and what liquid ,gass ,metal (discovered or not) etc , a person is put into ,that will be anywhere between 4 to 20 seconds. If you are fatter it will take longer ,since the cold has to penetrate the skin layer and the fat layer.

## Is a temperature below absolute zero possible?

Temperature in a gas can reach below absolute zero thanks to a quirk of quantum physics. It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time1.

## What happens to matter at absolute zero?

Absolute zero is the temperature at which the particles of matter (molecules and atoms) are at their lowest energy points. Some people think that at absolute zero particles lose all energy and stop moving. … Therefore, a particle cannot be completely stopped because then its exact position and momentum would be known.

## Has absolute zero been observed?

Nothing in the universe — or in a lab — has ever reached absolute zero as far as we know. Even space has a background temperature of 2.7 kelvins. But we do now have a precise number for it: -459.67 Fahrenheit, or -273.15 degrees Celsius, both of which equal 0 kelvin.

## What is the hottest temperature a human can survive?

108.14°FBody temperature: 108.14°F The maximum body temperature a human can survive is 108.14°F. At higher temperatures the body turns into scrambled eggs: proteins are denatured and the brain gets damaged irreparably.

## Why is 0 Kelvin not possible?

There’s a catch, though: absolute zero is impossible to reach. The reason has to do with the amount of work necessary to remove heat from a substance, which increases substantially the colder you try to go. To reach zero kelvins, you would require an infinite amount of work.

## What is the lowest temperature a human can survive?

The coldest recorded body temperature a person has ever survived is 56.7 degrees F (13.2 degrees C), according to Atlas Obscura.

## Who discovered absolute zero?

William ThomsonIn 1848, the Scottish-Irish physicist William Thomson, better known as Lord Kelvin, extended Amontons’ work, developing what he called an “absolute” temperature scale that would apply to all substances. He set absolute zero as 0 on his scale, getting rid of the unwieldy negative numbers.

## How cold is it in space near Earth?

-454.81 FahrenheitAs you probably know, space is already very, very cold — roughly 2.7 Kelvin (-270.45 Celsius, -454.81 Fahrenheit). This is mostly due to a lack of atmosphere and the vacuum-like nature of space — with very few molecules to energetically bounce around, there can be no heat.

## Do electrons stop moving at absolute zero?

Near absolute zero, electrons “continue to whiz around” inside atoms, says quantum physicist Christopher Foot of the University of Oxford. Moreover, even at absolute zero, atoms would not be completely stationary. They would “jiggle about,” but would not have enough energy to change state. … It’s energy is at a minimum.
