A thermos bottle is half-filled with water and is left open to the atmospheric air at 60°F and 35.00 percent relative humidity. If heat transfer to the water through the thermos walls and the free surface is negligible, determine the temperature of water when phase equilibrium is established. The saturation pressure of water at 60°F is 0.2564 psia. Use data from the steam tables. The temperature is °F.

A thermos bottle is half-filled with water and is left open to the atmospheric air at $60^{\circ} \mathrm{F}$ and 35 percent relative humidity. If heat transfer to the water through the thermos walls and the free surface is negligible, determine the temperature of water when phase equilibrium is established.
Water is being boiled at 1 atm absolute pressure in a jacketed kettle with steam condensing in the jacket at 115.6 degrees Celsius. The inside diameter of the kettle is 0.656 m and the height is 0.984 m. The bottom is slightly curved, but it will be assumed to be flat. Both the bottom and sides up to a height of 0.656 m are jacketed. The kettle surface for heat transfer is 3.2 mm stainless steel with k = 16.27 W/m-K. The condensing steam coefficient hi inside the jacket has been estimated as 10200 W/m^2-K. Predict the boiling heat transfer coefficient ho for the bottom surface of the kettle.

Suppose 0.400 kg of water initially at 40.0°C is poured into a 0.300 kg glass beaker having a temperature of 25.0°C. A 0.500 kg block of aluminum at 37.0°C is placed in the water and the system is insulated. Calculate the final equilibrium temperature of the system.
