Example 4.9: A cyclic process ABCA is shown in V-T V 2 C B diagram (Fig (a)). It is performed with a constant mass of V A ideal gas. How will T T, this transform to a (Fig (a) p-V digram?Example 4.10: Carnot engine: A Carnot engine receives 2.0 kJ of heat from a reservoir at 500 K, does some work, and rejects some heat to a reservoir at 350 K (a) How much work does it do? (b) how much heat is rejected. (c) what is its efficiency? engine
