Q$6$: In a different scenario, a fluid with a mass of $1kg$ at a pressure of $2{10}^5$Pas expands following the relationship $P{V}^2=K,$ where $K$ is a constant until the volume reaches twice its initial value. Next, the system is cooled at constant pressure until it returns to its initial volume. Finally, heat is applied to the system while the piston remains firmly locked in position until the pressure returns to the original value. We need to calculate the net work done if the initial volume is $0\mathrm{.}05m^3.$
