Q170 / 225 · JEE Main 2005 · Physics

Which of the following is incorrect regarding the first law of thermodynamics?

A
It is applicable to any cyclic process
B
It is a restatement of the principle of conservation of energy
C
It introduces the concept of the internal energy
Correct answer
D
It introduces the concept of the entropy

Solution

The first law of thermodynamics states the principle of conservation of energy. It introduces the concept of internal energy. And it is applicable for any cycle.

Hence, the correct answer is option: 'D'.
