- An engine has a hot reservoir of 520K and a low-temperature reservoir of 330K. What is the theoretical efficiency of this engine? Answer in units of %8000 J of heat from a hot reservoir is put into a reversible (Carnot) heat engine whose hot and cold reservoirs are at 600 K and 150 K respectively. How much work does the engine do?With 2.56×106 J of heat transfer into this engine, a given cyclical heat engine can do only 1.50×105 J of work.(a) What is the engine’s efficiency? (b) How much heat transfer to the environment takes place?
