Solution Summary

Calculates the maximum efficiency possible of a heat engine, and the least amount of heat that it must exhaust.

Solution Preview

Maximum efficiency= 1- T(cold)/T(hot)
T(cold)= 90 degrees Celsius = 363.15 =90+ 273.15
T(hot)= 500 degrees Celsius = 773.15 =500+ 273.15

Therefore maximum ...
