1.	A carnot engine is operated between two reserviors at temperatures of 500 K and 400 K. The engine receives 840 Joules of heat from the source in each cycle. Calculate (a) the amount of heat rejected to sink in each cycle (b) the efficiency of the engine, and (c) the work done in each cycle.
Answer» Solution :`Q _(2) = T _(2) Q _(1) //T_(1) = 400 XX 840 //500 = 672 J, ETA = 500 - 400 // 500 = 0.2, W = 0.2 xx 840 = 168 J`
