Question

A system of ideal gas undergoes a thermodynamic process in which the initial pressure and volume are equal to the final pressure and volume. Let △Q is the heat supplied to the system,△W is the work done by the system and △U is the change in internal energy. The correct option is:

• A. △Q=△W
• B. △U>0
• C. △U$\neq$0
• D. △U+△Q+△W=0
• E. △Q+△W=0

Answer 1

Answer: (A)

△Q=△W

Answer 2

The correct answer is (A):△Q=△W
