Text Solution

Verified by Experts
The correct answer is:
A

Isothermal: An isothermal process is defined as a process that occurs at a constant temperature. Therefore, A matches with III.
Adiabatic: An adiabatic process is one in which no heat is exchanged between the system and its surroundings ( ). Therefore, B matches with IV.
Isobaric: An isobaric process takes place at a constant pressure. Therefore, C matches with I.
Isochoric: An isochoric process occurs at a constant volume. Since work done ( ) is , if the volume doesn't change, no work is done. Therefore, D matches with II.
