The pressure-volume graph shows an engine cycle where the working substance is an ideal monatomic gas (? = 5/3). The process A-B is adiabatic. At point A, the pressure is 2.70×10^5 Pa and the volume is 0.0180 m^3. At point B, the volume is 0.0450 m^3. During a cycle,
calculate
(a) the heat added to the gas,
(b) the heat removed from the gas (stated as a positive number), and
(c) the net work done.
