mathematical equation for work done in isothermal irreversible process. The graph and the image of a piston at the top represent the slow expansion of a gas from an initial volume to a final volume you can vary these volumes with the sliders. 300 mmol of a perfect gas occupies 13 L at 320 K.

A work done w for iso-thermal reversible process is given by n no of mole. Therefore DeltaUT q w 0 and thus DeltaT 0 an isothermal condition. This Demonstration compares the thermodynamic processes of reversible and irreversible isothermal expansion of an ideal gas.
In this equation the symbol R is a constant called the universal gas constant that has the same value for all gasesnamely R 831 Jmol K.
PV const PVgamma const gamma barC_PbarC_V barC_V RbarC_V 1 RbarC_V The full derivation for the PV expressions is shown here. In contrast to adiabatic process in which n k and a system exchanges no heat with its surroundings Q 0. Begingroup in irreversible isothermal expansion formula for work done is WPexternalx change in volume. T temperature final volume initial volume.
