Problem

An ideal gas is initially at pressure

1.2\times10^{5}\,\text{Pa}

and volume

2.5\times10^{-3}\,\text{m}^3

. It is allowed to expand rapidly against a constant external pressure of

0.80\times10^{5}\,\text{Pa}

until its volume becomes

4.0\times10^{-3}\,\text{m}^3

. Calculate the work done by the gas in this process.
