Air with initial conditions is shown below, and it is allowed to leave a piston$-$cylinder device with a pair

$=-185$ of stops. $650$ kPa of pressure is required to move the piston's mass. $(1)$ What is the initial volume? $35$ kJ of heat is lost from the cylinder to the surrounding$($due to improper insulation$).$ Eventually, the piston starts to move to its final volume at $0\mathrm{.}15m^3,(2)$ what is the corresponding pressure, temperature at the final stage? $(3)$ Also, what is the boundary work. $(4)$ what is the mass escaped from the container? the exit temperature is assumed to be the average of the initial and final temperature in the device. $(40\%)$
