Question
A process can be reversible if
✓
Answer
(c)
A quasi-static process is a thermodynamic process that happens slowly enough for the system to remain in internal equilibrium. it means the change in one step system can be reversed after taking that step at any point of the process. The process should also be non-dissipative, i.e. there should not be any friction or air drag which results in loss of energy of system.
