The hot and cold reservoirs of a Carnot engine are 323°C and 66.7°C respectively. The temperature of the hot reservoir is raised by 39°C in order to increase the efficiency of the engine. (a) What is the efficiency after the increase in temperature? .374 Review the definition of efficiency for a Carnot engine. What units should you use for the temperature in this case?% (b) Instead of raising the temperature of the hot reservoir, if the temperature of the cold reservoir is decreased by 39°C, what would be the efficiency of the engine? .509 What are the temperatures of the hot and cold reservoirs now?%
