A temperature transformer is actually a device that transfers part of the heat, delivered to it at an advanced temperature, to a high temperature tank while rejecting the remaining part to a low temperature heat kitchen sink. In such a temperature transformer, 95 kJ of heat is supplied for 350 K. The maximum volume of heat in kJ that can be transferred to four hundred K, if the rest is definitely rejected to this can be used in 400 K, when snooze is turned down to a high temperature sink by 300 T is (a) 12. 50

(b) 18. 29

(c) 33. 33

(d) 57. 14

(c) ηs < ηc

(d) The sign of (ηs - ηc) depends on the operating fluids employed
