Five mole of a gas put through a series of change as shown below graphically in a cyclic process. The processes `A rarr B, B rarr C` and `C rarr A`, respectively, are

Options

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

Answer

A

Explanation

According to the graph, during the porcess `A - B`, the volume of the system does not change (isochroic). During the process `B rarr C`, both volume and temperature decrease to keep the pressure constant: `P = nRT//V` (isobaric).During the process `C rarr A`, the temperature of the system remains constants (isothermal).
