Pressure of a liquid is linear function of volume `P=a+bV.` Calculate work done for change in state form `(1"bar",2L)` to `(2"bar",5L)`:

An ideal gas is allowed to expand against a constant pressure of 2 bar from 10L to 50 L in one step. Calculate the amount of work done by the gas. If the same expansion were carried out reversibly, will the work done be higher or lower than the earlier case ? (Give that, 1 L bar = 100 J)

If 1.5 L of an ideal gas at a pressure of 20 atm expands isothermally and reversibly to a final volume of 15 L the work done by the gas in L atm is

2 moles of an ideal gas is compressed from ( 1 bar, 2 L) to 2 bar isothermally. Calculate magnitude of minimum possible work in change (in joules ). (Given : 1 bar L = 100 J, ln 2=0.7 )

One mole of an ideal gas is expanded from a volume of 3L to 5L under a constant pressure of 1 atm. Calculate the work done by the gas.
