Use the upper and lower absolute temperatures to compute the Carnot engine efficiency.
Wout/Qin = 1 - (300/443) = 0.3228
Divide 45000 J by the efficiency for the heat energy input, Qin.
Qin = 139400 J
Qout = 139400 - 45000 = 94,400 J
Divide that by the heat of fusion of ice, 334 J/g, for the final answer, in grams. They may want you to convert to kilograms
do i just divide it by a 1000 to convert. Because I am getting the wrong answer
nevermind it is correct. Thank you very much.
