Three moles of Helium gas are taken around thecyclea->b->c->a as shown in the figure below. Process abis atconstant volume, process bc is adiabatic and process ca isatconstant pressure. The temperature of the gas in states a, b andcare 300K, 600K, and 492K respectively. a) What is the total heat flow into or out of the gas for thecyclea->b->c->a? b) What is the efficiency of this engine?
