A dormitory room measures 4m x 6m x 6m. A student turns on a 150 watts fan before leaving the room on a summer day, hoping that the room will be cooler when she returns in the evening. Assume that all doors and windows are tightly closed, and there is no heat transfer through the walls and windows. At the start of the day, the room temperature is 15°C, and the pressure is 100 kPa. What will be the temperature inside the room when the student returns 10 hours later, given the specific heat value of air at room temperature?

A pressure cooker operates by cooking food at a higher pressure and temperature than is possible at atmospheric conditions. Steam is contained in the sealed pot, with a small vent hole in the middle of the cover, allowing steam to escape. The pressure is regulated by covering the vent hole with a small weight, which is displaced slightly by the escaping steam. Atmospheric pressure is 1 bar, the vent hole area is 7mm2, and the pressure inside should be 2.75 bar. What is the mass in kg of the small weight?
Jose is cooking sopas (chicken noodle soup) for Noche Buena. He finished early in the afternoon and wants to preserve it but the sopas is still too hot if it will be put directly on the refrigerator. The sopas has just boiled a hundred degree Celsius and the refrigerator wasn't powerful enough for the big container of the soup if it was warmer than 20 degrees Celsius. Jose found out that cooling it in a sink full of cold water, while the faucet is running with the water resulting to roughly constant temperature of 6 degrees Celsius, could bring the temperature of the sopas to 56 degrees Celsius in 8 minutes. Determine the value of the proportionality constant.
