A heat engine absorbs 2 500 J of heat from a hot reservoir and expels 1 000 J to a cold reservoir. When it is run in reverse, with the same reservoirs, the engine pumps 2 500 J of heat to the hot reservoir, requiring 1 500 J of work to do so. Find the ratio of the work done by the heat engine to the work done by the pump. Is the heat engine reversible?
