A diatomic ideal gas with

\gamma = 1.4

is compressed reversibly and adiabatically from an initial volume of

V_i = 0.010\,\text{m}^3

and pressure

P_i = 1.0\times10^{5}\,\text{Pa}

to a final volume of

V_f = 0.005\,\text{m}^3

. (a) Determine the final pressure

P_f

. (b) Hence calculate the change in internal energy

\Delta U

of the gas.
