Figure shows four PV diagrams. Which of these curves represent isothermal and adiabatic processes?

A

C and D

B

A and C

C

A and B

D

B and D.

Text Solution

Verified by Experts

The correct Answer is:
a
In curves A and B, pressure and volume both increase. Therefore, temperature must rise and heat must be supplied/work is done. Therefore A and B cannot be required curves. Out of C and D, slope of C is smaller. Therefore, C is isothermal curve and D is adiabatic curve.
