You design a steam engine that uses water at the freezing point and water at the boiling point (both at regular atmospheric pressure) to generate useful work. Calculate the Carnot efficiency of this heat engine. You invent a superheated steam engine that can generate steam as hot as 590 °C. If this heat engine uses water at the freezing point as the cold object, calculate the Carnot efficiency of this new heat engine.
