A heat engine that has maximum efficiency starts working by using 1 kg of water with initial temperature Ti = 373K as a hot reservoir, and 1 kg of ice at T0 = 273K as its cold reservoir. As the engine goes through cycles, the water cools, and the ice melts. At some point, all of the ice will be melted. (a) What is the temperature of the water reservoir at that time? (b) What is the maximal amount of...

An iron boiler of mass 180 kg contains 770 kg of water at 21 ∘C. A heater supplies energy at the rate of 58,000 kJ/h. The specific heat of iron is 450 J/kg⋅C∘, the specific heat of water is 4186 J/kg⋅C∘, the heat of vaporization of water is 2260 kJ/kg⋅C∘. Assume that before the water reaches the boiling point, all the heat energy goes into raising the temperature of the iron or the steam, and none goes to the vaporization...

A piston-cylinder apparatus contains 4 kg of saturated liquid water at 35˚C. The piston’s cross sectional area is 0.06 m2 , and initially it is resting on stops, enclosing a volume of 0.03 m3 . To raise the piston, a pressure of 300kPa has to be applied. Heat is transferred until the volume is 0.075 m3 , at which point the piston encounters a linear spring. To deflect the spring 1 m, a force of 360 kN is required. More...
