1. An engine can turn 750 J of input energy into 125 J of useful work. Calculate the remaining energy this engine cannot convert into useful work. 2. Suppose a steam engine receives steam at 600K. The engine uses part of this thermal energy for work. It exhausts the rest to a condenser at a temperature of 350K. What is the maximum efficiency of this steam engine?
