One mole of an ideal monoatomic gas at pressure P , volume V and temperature T is expanded isothernmally 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 (Round off 2 decimal places)
