What is the temperature at point B?What is the work done BY the gas in the transition A to B? (Signs are important!)What is the heat input into the gas for the transition A to B? (Signs are important!)What is the work done in the transition B to C? (Signs are important!)What is the heat input into the gas for the transition B to C? (Signs are important!)For the constant temperature transition C to A, 623.83246 J of heat are taken out of the gas. What is the work done ON the gas in the transition?What is the efficiency of this heat engine? What is the efficiency of a Carnot cycle running between the lowest and highest temperature of the cycle above?
