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 516° and a maximum pressure of 5.00 atm . with a heat input of 405 j per cycle, you want 325 j of useful work. part a)
find the temperature of the cold reservoir.
express your answer using two significant figures.
part b)
for how many cycles must this engine run to melt completely a 9.00-kg block of ice originally at 0.0°c, using only the heat rejected by the engine?
