7. Northern California is home to the largest geothermal power plant in the world. Its heat source is water at a temperature of 195 °C (note: it is under high pressure, which keeps it from vaporizing). This heat is used to create steam to drive a turbine. The excess heat is vented to the outside air at 25.0 °C. If the power plant engine uses the Carnot cycle, what is its efficiency? For comparison, also find the Carnot efficiency for a power plant that uses a coal furnace, at a temperature of 1850 °C, as a heat source and also vents to the outside air. 36.3% 86.0%
