Clausius Inequality

A system undergoes a cycle while receiving 1200 Icl by heat transfer at a temperature of 600 K and discharging 600 k.I by heat transfer at (a) 200 K, (b) 300 K, (c) 400 K. Using Clausius Inequality, determine the nature of the cycle in each of these cases. (Watch "Clausius Inequality Examples")
