Question

what will happen if the matter is cooled and cooled upto absolute zero that is 275 kelvin then what will happen?​

Answer 1

Answer:

Solution:-

• First of all I don't think we have achieved absolute zero state yet and I think its impossible to attain. So if you touch a body which is nearly 1-2 K with your hand, your senses will freeze and you wont be able to sense anything using your hand. and from the heat gained from your hand the object will retain back to its normal state with in a fraction of seconds

Answer 2

Explanation:

Reaching absolute zero is not permitted by thermodynamics as when an object is cooled a certain amount of work is done in cooling the object and as the temperature of the object to be cooled decreases the amount of work required to cool it further increases, so to cool an object to absolute zero infinite work is required which is not possible. So absolute zero cannot be reached.

But assuming we somehow managed to reach absolute zero, then according to quantum mechanics all motion will cease and the matter will be in its ground state or the minimum energy state (also called as zero point energy). No further decrease in energy is possible. As entropy at absolute zero is zero, there will be perfect order, the matter will behave as a pure crystal.

Although we can't reach absolute zero we have achieved temperatures close to absolute zero, so we have an idea of how the matter will behave at such temperature.

Superconductivity, superfluidity all appear at such temperature, near absolute zero matter reaches a state we define as bose-einstein condensate, a state where ordinary matter follows bose-einstein statistics.
