Assume that the turbines at a coal-powered power plant were upgraded, resulting in an improvement in efficiency of 3.32%. Assume that prior to the upgrade the power station had an efficiency of 36% and that the heat transfer into the engine in one day is still the same at 2.50 x 10¹⁴ J. 

(a) How much more electrical energy is produced due to the upgrade?

(b) How much less heat transfer occurs to the environment due to the upgrade?
