Question

Which of the following is true for a reversible process

• A. The pressure and temperature of the working substance and the surroundings should differ at any stage
• B. The process should take place very slowly during operation.
• C. The process should take place very fast during operation
• D. Energy should be lost due to conduction or radiation during operation

Hint:

Reversible processes also require no net energy losses due to friction, conduction, or radiation.

Answer 1

The Correct Option is B

For a thermodynamic process to be reversible, the system must be in near-equilibrium at each stage, requiring infinitesimally small differences in pressure/temperature, and hence the process proceeds very slowly without dissipative losses.
