Question

One mole of an ideal gas in initial state A undergoes a cyclic process ABCA as shown in the figure. If the pressure at A is $P_0$, then which of the following statement(s) is/are correct?

• A. Internal energies at A and B are same.
• B. Work done by the gas in process AB is $P_0V_0$ In 4.
• C. Change in internal energy in complete cycle ABCA is greater than zero.
• D. Temperature at C is 4$T_0$.

Answer 1

Answer: (A), (B)

Internal energies at A and B are same.

Answer 2

The correct option is: A and B
