A cyclic heat engine operates between the temperatures of 825° C and 555° C. Its efficiency is one-third the efficiency of an ideal
(Carnot) engine that operates between these same two
temperatures. Calculate how much input heat is required for this
engine to perform 1.00 kilojoules of work.
O 12.2 kJ
9.17 kJ
