pressure from 273 K to 373 K. If 20.0 J of work is done by the gas during this process, what is the mass of helium present? 5. A heat engine absorbs 2.00 kJ from a hot reservoir at 550 K and expels 1.15 kJ to a cold reservoir at 300 K in each cycle. (a) What is the engine's efficiency? (b) How much work is done by the engine in each cycle? (c) What is the power output of the engine if each cycle lasts 0.300 s?
