A certain heat engine operates on the PU diagram loelow. It contains 4.? moles of a diatomic ideal gas. The process that takes the gas from point c to point a is isothermal. \"P ( k'PaO What the temperature of the gas at state c? What temperature is the gas at state a? How much heat is addedfremoved from the gas over the path cto-a? What is the pressure of state a? What is the temperature of state in? Find the work done and heat exchanged [either can be positive or negative] for the path atob Find the work done and heat exchanged for the path lotoc. Find the efciencyr of the engine. I. Would the engine he more, or less efficient if the gas were diatomic? rho L151 o'ga 'a'ns
