Which of the following processes is reversible?

Question

G1 Physics · Accepted Answer

Step 1: A reversible process can be reversed by an infinitesimal change in external conditions without net change in system plus surroundings. Step 2: Heat transfer through a finite temperature difference (conduction or radiation) is irreversible. Step 3: Electrical resistance heating converts organised electrical energy to dissipated thermal energy and is irreversible. Step 4: Isothermal compression can be performed quasi-statically with infinitesimal pressure difference and heat exchange with…
