A certain heat engine operates between 50 ° C and 130 ° C. (a) Calculate the maximum work that can be done for each 2.0 kJ of heat supplied by the hot source. (b) How much heat is discharged into the cold sink in a reversible process for each 2.0 kJ supplied by the hot source? (c) To increase the theoretical efficiency by 5 %, to what temperature would the hot source have to be raised if the temperature of the cold source were constant?
