Q. Three moles of an ideal gas kept at a constant temperature at

300 K

are compressed from a volume of

4 L

1 L

. The work done in the process is

A certain mass of gas is expanded from (1L, 10 atm) to (4L, 5 atm) against a constant external pressure of 1 atm. If initial temperature of gas is 300K and the heat capacity of process is $50 J /^{\circ} C$ . Then the enthalpy change during the process is:
(1L atm = 100 J)
