Question

Which of the following states that absolute zero cannot be reached

A. the first law of thermodynamics

B. the second law of thermodynamics

C. the third law of thermodynamics

D. the second and third laws of thermodynamics

Answer 1

C. Is the correct answer.

Answer 2

3rd law of thermodynamics

Explanation:

According to the third law of thermodynamics, at absolute zero the entropy of a system is constant or the entropy is equal to zero. The randomness in a system is referred to as its entropy.

`S_(T=0)=0`

When the temperature on the Kelvin scale is equal to zero, it is called an absolute zero condition.

Hence, the correct option is (c) " the third law of thermodynamics ".
