A gas is compressed from an intiail condition $295K,10$ bars to a final condition $610K,60$ bars. T gas follows the following equation of state:

$z=1+\frac{aP}{T^{0\mathrm{.}25}}$

where, $a=-0\mathrm{.}0094[\frac{K^{0\mathrm{.}25}}{\frac{?}{?}}$bar $]$ and $P$ is in bars

Note: $a$ is negative. There is a minus sign.

Assume that the $Cp$ of gas is nearly constant and equal to $3\mathrm{.}7R$ where $R$ is gas constant.
