Consider a reversible cycle involving two isobaric and two isochoric (iso-volumic) processes, operating over ranges in volume of 2-5 m³ and pressure of 2-5 atm. The cycle uses 100 mol of an ideal gas for which the internal energy is given as U = nRT. a) Draw the cycle in a fully-labelled P-V indicator diagram, indicating the direction if operated as a heater, and label the corners of the cycle with the temperatures of the gas. b) Calculate the efficiency of the cycle if operated as a heater.
