4) The turbines at a coal-powered power plant were just upgraded, resulting in an improvement in efficiency of 3.32 percentage points. Assume that the heat transfer into the heat engine in one day is still the same at 2.25 × 10¹4 J. a) How much more electrical energy is produced due to the upgrade in J per day? Assume that all the work done by the plant goes into producing electricity. b) What is the change in heat transfer to the environment due to the upgrade in J?
