0.28 mmol of a perfect gas occupies12.7L at 310 K after that volume increase by 3.3 L Calculate the work done when the gas expands (i) isothermally against a constant external pressure of 0.25 atm

0.28 mmol of a perfect gas occupies12.7L at 310 K. after that volume increase by 3.3L. Calculate the work done when the gas expands. isothermally and reversibly

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.

0.28 mmol of a perfect gas occupies12.7L at 310 K. Calculate the work done when the gas expands. into vacuum, until its volume has increased by 3.3 L.

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.

Derive an expression for work when gas expands against constant external pressure.

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) .
