Given 2 identical ideal machines. Initially, both machines have a hot tank temperature and a cold tank temperature . The temperature of the hot tank of the first machine is increased by and the temperature of the cold tank of the second machine is decreased by . In which case does the efficiency increase more? Calculate the efficiency ratio of the first to the second machine if a the initial temperature of the hot tank is 200 °C.
