A heat engine with 0.500mol of a monatomic ideal gas initially fills a 1000cm^3 cylinder at 700K . The gas goes through the following closed cycle: - Isothermal expansion to 5000cm^3 . - Isochoric cooling to 200K . - Isothermal compression to 1000cm^3 . - Isochoric heating to 700K
A) How much work does this engine do per cycle?
B) What is its thermal efficiency?
