One mole of an ideal gas at pressure `P_(0)` and temperature `T_(0)` is expanded isothermally to twice ist volume and then compressed at constant pressure to `(V_(0) // 2)` and the gas is brought bac to original state by a process in which `P alpha V` (pressure is direclty proportional to volume). The correct temperature of the process is

Options

A.
B.
C.
D.

Answer

C

Explanation

c. Process `AB` is isothermal expansion, `BC` is isobaric compression and in process `CA`
`P porp (nRT)/(P) implies P^(2) prop T`
