JEE Main 2025 — 2 April, Morning Shift — Question 53

In an adiabatic process, which of the following statements is true?

Option A:
The molar heat capacity is zero
Correct
Option B:
The molar heat capacity is infinite
Option C:
The internal energy of the gas decreases as the temperature increases
Option D:
Work done by the gas equals the increase in internal energy

Answer: A

Step-by-step solution
