###### FREE Expert Solution

When a gas is compressed by an adiabatic process, we have the condition:

$\overline{){\mathbf{P}}{{\mathbf{V}}}^{{\mathbf{\gamma }}}{\mathbf{=}}{\mathbf{c}}{\mathbf{o}}{\mathbf{n}}{\mathbf{s}}{\mathbf{t}}{\mathbf{a}}{\mathbf{n}}{\mathbf{t}}}$

This implies that:

$\begin{array}{rcl}{{\mathbf{P}}}_{{\mathbf{1}}}{{{\mathbf{V}}}_{{\mathbf{1}}}}^{{\mathbf{\gamma }}}& \mathbf{=}& {{\mathbf{P}}}_{{\mathbf{2}}}{{{\mathbf{V}}}_{{\mathbf{2}}}}^{{\mathbf{\gamma }}}\\ {{\mathbf{P}}}_{{\mathbf{2}}}& \mathbf{=}& \frac{{{\mathbf{P}}}_{{\mathbf{1}}}{{{\mathbf{V}}}_{{\mathbf{1}}}}^{{\mathbf{\gamma }}}}{{{{\mathbf{V}}}_{{\mathbf{2}}}}^{{\mathbf{\gamma }}}}\end{array}$
