Vedclass · Answer

(D) reversible process is defined as a process that can be reversed without leaving any trace on the surroundings. For a process to be reversible,it must satisfy two main conditions: $1$. The process must be quasistatic (infinitely slow),ensuring the system remains in thermal and mechanical equilibrium with its surroundings at every stage. $2$. There should be no dissipative effects such as friction,viscosity,or electrical resistance,meaning the loss of energy must be zero. Therefore,option $(d)$ is the most comprehensive answer as it covers both the absence of energy loss and the requirement for the process to be quasistatic. Mathematically,for a reversible cycle,$\oint \frac{dQ}{T} = 0$.

For a reversible process,the necessary condition is:
