0A heat transformer is device that transfers a part of the heat, supplied to
it at an intermediate temperature, to a high temperature reservoir while
rejecting the remaining part to a low temperature heat sink. In such a heat
transformer, 100 kJof heat is supplied at 350 K. The maximum amount of
heat in kJ that can be transferred to 400 K, when the rest is rejected to a
heat sink at 300 Kis
