Question $1$:

A cylinder device fitted with a piston contains initially argon gas at $100$ kPa and $27C$ occupying a volume

of $0\mathrm{.}4m^3.$ The argon gas is first compressed while the temperature is held constant until the volume reaches

$0\mathrm{.}2m^3.$ Then the argon is allowed to expand polytropically with $n=1\mathrm{.}2$ until the volume becomes $0\mathrm{.}6m^3.$

Determine $($a$)$ the work in the isothermal process in kJ $.($b$)$ the work in the polytropic process in kJ $.($c$)$ the

total amount of net heat transferred to the argon in kJ$.$ Argon is an ideal gas with constant specific heats
