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.

∙ 7y agoApparently this is a consequence of the Third Law of Thermodynamics, which states that the entropy of a substance, at absolute zero, would be exactly zero.It would require an infinite number of steps to actually achieve absolute zero.
However, in practice, temperatures very close to absolute zero (less than a microkelvin) have been achieved.

Which organism which does not show molecular movement?
Molecules are constantly in motion. Whether they are free moving, as in a gas, or are vibrating in place, as in a solid object, they still move. an object that has reached the theoretical temperature of absolute zero would have no molecular motion, but absolute zero is purely theoretical and is thereby unattainable.
Is absolute zero is equal to -273 degrees on the Kelvin scale?
Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.Kelvin is defined in such a way that absolute zero is zero Kelvin.
Is absolute zero measured in kelvins?
Yes, absolute zero is zero degrees Kelvin.
Did they reach absolute zero on Pluto?
Although very cold, Pluto is still a few degrees off absolute zero. Zero kelvin is absolute zero, Plutos minimum reaches around 33 kelvin, 33 degrees above absolute zero.
Why can't -5K exist?
0K is absolute zero, meaning that the system contains zero thermal energy. Temperatures below absolute zero are impossible.

What is the absolute vaue of zero?
The absolute value of zero is zero.

What is the special name for zero degree Kelvin?
Absolute zero.
What is absolute zero Celsius?
Absolute zero (zero kelvin) is -273.15 C
Is zero degrees Kelvin absolute temperature?
It is absolute zero.
What would happen to an atom if it reached absolute zero?
There is nothing "magic" about absolute zero. It's unattainable in practice, but theoretically nothing in particular would "happen" if an atom did achieve that temperature. If you were hoping for an answer like "the electrons would stop moving and collapse into the nucleus", no, sorry, that's not going to happen.
Why is absolute zero important?
absolute zero is the essence of nothing and nothing is a quantity of zero.
Is absolute zero measured in kelvins?
Yes, absolute zero is zero degrees Kelvin.
What is it called when molecular motion stops?
Absolute zero is the theoretical temperature at which all atomic motion stops. However, this temperature is unattainable, because it represents a complete lack of energy within particles of matter. Even in deep space, this temperature cannot be reached so, like the speed of light, it is a scientific limit which can only be approached. On the Kelvin scale it's 0, on the Celsius scale it's -273.16.
Can an numbers absolute value be zero?
The only number whose absolute value is zero is zero. This is because a number's absolute value is its distance from zero on the number line.
Do molecules disappear at absolute zero?
No. They are as frozen still as they can ever be. It is said to be scientifically impossible to actually reach absolute zero.
