One mole of an ideal monoatomic gas expands isothermally against constant external pressure of 1 atm from initial volume of 1L to a state where its final pressure becomes equal to external pressure If initial temperature of gas is 300 K then total entropy change of system in the above process is R 0 082 L atm mol 1 K 1 8 3 J mo1 K 1 1 0 2 Rin 24 6 3 Rin 2490 4 RIn 24 6
