Following is the

P

V

plot of a cyclic process

1 \rightarrow 2,2 \rightarrow 3,3 \rightarrow 4,4 \rightarrow 1

, denoted as I, II, III and IV respectively for a system of one mole of an ideal gas. Assume that there is heat exchange between the system and surroundings only in II and IV. Which of the following is/are correct? Following is the P vs V plot of a cyclic process 1 arrow 2,2 arrow 3,3 arrow 4,4 arrow 1 , denoted as I, II, III and IV

Following is the P vs V plot of a cyclic process 1 arrow 2,2 arrow 3,3 arrow 4,4 arrow 1 , denoted as I, II, III and IV

Options

AIn II and IV $\Delta \mathrm{S}$ is zero
BIn I and III, $\Delta \mathrm{S}$ is zero
CI and III are isothermal and reversible
DIn II and IV, change in internal energy of the gas $(\Delta \mathrm{U})$ is zero

Correct answer

B. In I and III, $\Delta \mathrm{S}$ is zero
