Question: You are designing a Carnot engine that has 2 mol of CO2 as its working substance; the gas may be treated as ideal. The gas

You are designing a Carnot engine that has 2 mol of CO2 as its working substance; the gas may be treated as ideal. The gas is to have a maximum temperature of 527°C and a maximum pressure of 5.00 atm. With a heat input of 400 J per cycle, you want 300 J of useful work.
(a) Find the temperature of the cold reservoir.
(b) For how many cycles must this engine run to melt completely a 10.0-kg block of ice originally at 0.0°C, using only the beat rejected by the engine?
