Acarnot engine is held between a furnace with a constant temperature of 400° c and the outside environment at a constant temperature of 30° c. there is a leak in the system which allows heat to escape directly from the furnace to the environment. the efficiency of the engine, including the effect of the leak, is 0.25. what is the ratio of the heat that flows into the carnot engine (qh1) to the heat that flows directly to the environment (qh2)? qh1/qh2 =
