An ideal mono-atomic gas (ratio of specific heats

\gamma = 5/3

) undergoes a reversible adiabatic expansion. The initial state is

P_i = 2.0\times10^{5}\,\text{Pa}

V_i = 0.020\,\text{m}^3

. After expansion the pressure falls to

P_f = 8.0\times10^{4}\,\text{Pa}

. Calculate the work done by the gas during the expansion.
