An ideal gas is taken through these thermodynamic cycles Draw the ABCD cycle on a P-V diagram and determine all of the unknown temperatures, pressures, volumes at points A, B, C, D in terms of n, R, Pa, Va. What is the net mechanical work done by the gas over the entire cycle? How much heat is absorbed by the gas during each leg of the cycle? Explain why this is the cycle of a heat engine, and determine it's efficiency.
