Question

Five moles of a gas is put through a series of changes as shown graphically in a cyclic process. The processes $A\to B,B\to C$ and $C\to A$ respectively are

• A. isochoric, isobaric, isothermal
• B. isobaric, isochoric, isothermal
• C. isothermal, isobaric, isochoric
• D. isochoric, isothermal, isobaric

Answer 1

Answer: (A)

Process $A\to B$ is isochoric, i.e., volume remains constant.
Process $B\to C$ is isobaric, i.e., pressure remains constant.
Process $C\to A$ is isothermal, i.e., temperature remains constant.
