For the process, 1 Ar (300 K, 1 bar) `rarr` 1 Ar (200 K, 10 bar), assuming ideal gas behaviour, the change in molar entropy is

1 mole of real gas is subjected to a process from (2 "bar", 40 lit., 300K) to ( 4 bar , 30 lit., 400K) . If Change in interal energy is 20 kJ then calculate enthalpy charge for the process.

In an isothermal process at 300 K, 1 mole of an ideal gas expands from a pressure 100 atm against an external pressure of 50 atm. Then total entropy change ("Cal K"^(-1)) in the process is -
