In a Carnot cycle $A BC D$ ( $A \to B$ isothermal expansion, $B \to C$ adiabatic expansion, $C \to D$ isothermal compression, $D \to A$ adiabatic compression), heat is exchanged with the surroundings only during:

Options:

Answer:

Solution:

Adiabatic steps have $Q = 0$ . Heat is absorbed in the isothermal expansion $A B$ and rejected in the isothermal compression $C D$ . A.
