Two moles of a monatomic sa.s at 27 °C and three moles of a diatomic gas at the same temperature expand adiabatically. If the work done by each gas during the expansion is 4157 J. the ratio of the final temperatures of the monatomic gas to that of the diatomic gas is
(Universal gas constant = 8.314 Jmol−1K−1)
