Isothermal expansion = isothermal heat addition or absorption.

Isothermal compression = isothermal heat rejection.

During the isothermal expansion process, heat is rejected. So the answer is incorrect.

There are 2 isothermal process (heat addition, heat rejection).

Heat rejection at isothermal expansion is correct.

Option (A) correct.

It is Carnot Cycle for an engine and not Reversed Carnot cycle used in Refrigeration theory. The given answer is correct.

But in an isothermal compression the heat is added.

Hari said:   9 years ago
Isothermal compression (Heat Addition) Heat source added.

Isothermal Expansion (Heat Rejection) Sink-source rejected.

No; isothermal compression takes heat.

And isothermal expansion release heat.

How can is this possible?
