One mole of an ideal monatomic gas at pressure p, volume v and temperature t is expanded isothermally to volume 4v. thereafter, the gas is heated isochorically

One mole of an ideal monatomic gas at pressure P, volume V and temperature T is expanded isothermally to volume 4V. Thereafter, the gas is heated isochorically (at constant volume) till its pressure becomes P. If R is the universal gas constant, the total heat transfer in the process, in units of RT is .
