A heat engine using a diatomic gas follows the cycle shown in the $pV$ diagram.

The gas starts out at point $1$ with a volume of $V_1=318c{m}^3,$ a pressure of $p_1=147$kPa, and a temperature of $317$ K $.$

The gas is held at a constant volume while it is heated until its temperature reaches $455$ K $($point $2).$

The gas is then allowed to expand adiabatically until its pressure is again $147$ kPa $($point $3).$

The gas is maintained at this pressure while it is cooled back to its original temperature of $317$ K $($point $1$ again$).$

For the first stage of this process, calculate in joules the heat $Q_{12}$ transferred to the gas and the work $W_{12}$ done by the gas.

$Q_{12}=$
