Question

it is possible to attain a temperature equal to absolute zero ? explain​

Answer 1

Answer:

Very low temperatures

Absolute zero cannot be achieved, although it is possible to reach temperatures close to it through the use of cryocoolers, dilution refrigerators, and nuclear adiabatic demagnetization. The use of laser cooling has produced temperatures less than a billionth of a kelvin.

Answer 2

Answer:

It is not possible to get absolute zero because the work required to remove heat from a substance increases when you try to cool it more. But it is possible to reach temperatures close to it cryocoolers dilution refrigerators etc.

hope it helps :)
