The figure shows the P-V plot of an ideal gas taken through a cycle ABCDA. The part ABC is a semi-circle and CDA is half of an ellipse. Then,

A

the process during the path `A rarr B ` is isothermal

B

heat flows out of the gas during the path `B rarr C rarrD`

C

work done during the path `A rarr B rarr C` is zero

D

positive work is done by the gas in the cycle `ABCDA`

Text Solution

Verified by Experts

The correct Answer is:
B, D
(i) For isothermal process curve should be hyperbola.
(ii) Work done & change in internal energy are both negative.
(iii) For higher pressure volume is increasing and lower pressure volume is decreasing .
