Absolute zero has not been achieved, temperature is simply proportional to the speed of the molecules, and absolute zero is the temperature that corresponds to a molecule that is not moving at all. While it happens all the time instantanously, we cannot get groups of molecules to stop moving altogether. We have gotten molecules extremely close to that speed using magnets to pull energy from molecules.

What is the temperature of a substance when it has lost its thermal energy?

When all thermal energy is lost, the temperature of the substance is Zero Kelvin, or absolute zero. So far, this temperature has not been achieved yet.


What is the lowest temperature ever achieved in laboratory?

The coldest possible temperature is absolute zero - defined as 0o kelvin. In 2000 in Helsinki, a temperature of 100 pK (1×10−10K) was achieved.


When does absolute zero occur?

Absolute zero is the theoretically coldest temperature. It is not possible to actually achieve absolute zero, only to approach it. In laboratory experiments, temperatures below one microkelvin have been achieved - i.e., less than a millionth of a degree above absolute zero.


What is absolute zero and why is it impossible to achieve it?

Absolute zero is the lowest possible temperature. Basically, the closer you get to absolute zero, the harder it becomes to get even closer. However, it is possible to get very, very close - temperatures of less than a microkelvin, i.e., a millionth of a degree above absolute zero, have already been achieved.


What is meant by the absolute zero of temperature?

Absolute zero is achieved when the atoms in a substance stop moving completely. At -273.15C or -459.67F. True absolute zero cannot be reached, but it can be approached to within a few millionths of a degree.


What is the lowest temperature ever achieved?

The record-low temperature was reached in a piece of rhodium metal, which was cooled to 100 pK. This is one-degree above absolute zero, a temperature that can never be reached.


What is the difference between ambient temperature and absolute temperature?

Ambient temperature is the current temperature of the surrounding environmentAbsolute temperature is the temperature of something relative to absolute zero


What can be the coldest temperature?

Absolute 0, But it hasn't been attempted yet.


Difference between absolute zero and absolute temperature?

Absolute zero is the lowest possible temperature (zero kelvin). Absolute temperature is the temperature, measured from absolute zero - in other words, any temperature, measured (usually) on the kelvin scale.


Where on earth can you find absolute zero?

Absolute zero can not be reached. It can be approached, though. In laboratories on Earth, temperatures of less than a microkelvin (less than a millionth degree above absolute zero) have been achieved.


What is the coldest anything can get?

absolute zero is the coldest anything can get -273.15º C. its never actually been able to be achieved by anyone


Is there absolute maximum temperature like absolute zero minimum temperature?

No.


Why is absolute zero unattainable?

To lower the temperature, you have to move heat from warmer to colder. If you were trying to cool something down to absolute zero, you would have to have a sink that was even colder. Absolute zero is a state where all the energy has been removed - and you can't get less than no energy, so you can't have a sink to absorb energy from something above absolute zero to reduce it to absolute zero. ... there are other explanations, but I've observed that this one is often the easiest for people to grasp.


What happens to the movement of gaseous molecules at the absolute zero temperature?

# No real substances are gaseous at temperatures near absolute zero; # Absolute zero cannot be physically achieved (though we can get pretty close). Taken together they make the question irrelevant to any real situation.


What is the difference between kelvin and absolute kelvin?

Kelvin is the absolute temperature - a temperature where absolute zero, the lowest temperature possible, is defined as zero. Therefore, in the phrase "absolute Kelvin", the word "absolute" seems redundant.


Is absolute temperature is same like absolute zero?

No, but they are related. Absolute zero is the coldest possible temperature. Absolute temperature is the temperature above this coldest possible temperature - i.e., how much hotter is it than the coldest theoretically possible temperature. Celsius temperature isn't absolute. It starts from the temperature of freezing water, and it needs negative numbers for anything colder than that. Fahrenheit temperature isn't absolute. It says that zero is 32 degrees colder than freezing water, and it needs negative numbers for anything colder than that. Absolute temperature starts from absolute zero. Nothing is colder than that, so absolute temperature is never a negative number.


Has the Bose-Einstein Condensate ever been achieved?

Yes. It is now regularly achieved, despite the fact that the required temperature is less than a microkelvin.


Has anything ever been taken to the temperature of absolute zero?

yes, a rubber chicken has


Weather No system can reach absolute zero temperature?

It is an slandered temperature that has been taken as reference. No system has this temperature some exception are there for perpection systems.


What are the absolute units of temperature?

If you mean unit for absolute temperature, the Kelvin is usually used.


Who defined the absolute temperature scale?

The absolute temperature scale was defined by Lord Kelvin.


What temperature would you encounter at Absolute Zero?

Simple answer: -273.15 degrees celcius. Less simple answer: Absolute zero IS the temperature. Temperature is the average speed of the particles in a substance. The term "Absolute Zero" means that the speed of every single particle in a mass is absolutely zero; none of the particles are moving. If a single particle moves within the given mass, the average must be more than zero, and, consequently, the mass has not achieved Absolute Zero. There is no known way to bring a mass on Earth to Absolute Zero. It would take an infinite amount of energy to get to there.


Absolute zero temperature?

Absolute zero temperature is 0 kelvin that is -273 degree Celsius


What is the absolute temperature of a gas?

Absolute temperature is the old term for degrees Kelvin. The temperature scale starts at absolute zero, and rises in increments of 1K which are the same "size" as 0C.
