Calculate the work done during synthesis of `NH_3` in which volume changes from `8dm^3` to `4dm^3` at a Constant external pressure of 43 bar. In what direction the work energy flows?

Calculate the work done when 5 moles of an W, ideal gas expanded from 1m^3 to 10m^3 against a constant external pressure of 2.026 xx 10^2 Nm^(-2) .

Calculate the work done during compression of 2 mol of an ideal gas from a volume of 1m^(3) to 10 dm^(3) 300 K against a pressure of 100 KPa .

300 m mol of an ideal gas occupies 13.7 dm^3 at 300 K . Calculate the work done when the gas is expanded until its volume has increased by 2.3 dm^3 (a) isothermally against a constant external pressure of 0.3 bar (b) isothermally and reversibly (c) into vaccum.

300 mol of perfect gas occupies 13L at 320k Calculate the work done-in Joules when the gas expands by volume of 3L more : Isothermally against a constant external pressure of 0.2 atm.
