A reciprocating compressor is a device that compresses air by a back$-$and$-$forth straight$-$line motion, like a piston in a cylinder. Consider a reciprocating compressor running at $200$ rpm $.$ During a compression stroke, $1\mathrm{.}20$ mol of air is compressed. The initial temperature of the air is $390$ K$,$ the engine of the compressor is supplying $8\mathrm{.}6$ kW of power to compress the air, and heat is being removed at the rate of $1\mathrm{.}0$ kW $.$

Part A

Calculate the temperature change per compression stroke.
