An ideal gas expands from 26.0 L to 80.0 L at a constant pressure of 1.00 atm. Then, the gas is cooled at a constant volume of 80.0L back to its original temperature. It then contracts back to its original volume without changing temperature. Find the total heat flow, in joules, for the entire process. total heat flow:

An ideal gas with Cv = 5/2R, and γ = 1.4 starts at a volume of 2.0m^3, a pressure of 3.0 × 10^5Pa, and a temperature of 300K. The gas undergoes an isochoric cooling where its pressure decreases to 1.0 × 10^5Pa. It then undergoes an adiabatic contraction until its pressure returns to 3.0×10^5Pa. It finally undergoes an isobaric heating until it returns to a volume of 2.0m^3. What is the efficiency of this heat engine?
