Question

1. Thetemperature of the heat reservoirs for a Carnot cycle (reversible)engine are T_h = 1200 K and T_c = 300 K. (a)Calculate the efficiency of this engine to two significan figures.(b) If w = -100 kJ (note that the sign means work is done by thesystem) calculate q₁ and q₂ in kJ. Enter themin that order to two significant figures. (c) The same engine canbe operated in reverse, i.e. as a heat pump which is an engine thatturns work into heat. If w = +100 kJ, calculate q₁ andq₂ in kJ (note that the signs change). (d) Suppose itwere possible to have an engine with a higher efficiency of 0.80.If for this engine w = -100 kJ, calculate q₁ andq₂ in kJ. (e) Now let
