Q. Which of the following processes is reversible ?
A) Transfer of heat by radiation
B) Electrical heating of a nichrome wire
C) Transfer of heat by conduction
D) Isothermal compression
Explanation
[Solution from source] A quasi-static isothermal compression can be retraced through the same equilibrium states, so it is reversible. Heat flow by conduction or radiation across a finite temperature difference and Joule heating are irreversible. Answer (4).
