A concrete swimming pool 12 m x 6 m x 2.5 m is filled with water to within 6 mm of the top when the temperature is 10 oC. The coefficient of linear expansion of the concrete is 0.90 x 10^-5/oC. What will happen to the water level as the temperature rises? If it rises at what temperature will the water begin to overflow?
A steel tape measure is calibrated at 70 oF. A reading of 120 ft is obtained when it is used to determine the width of building at 0 oF. What is the true width of the building at 0 oF?
A 300 g aluminum pot containing 0.50 L of water is placed on the 1 kg iron hot plate on an electric stove. The heating element of the hot plate is rated at 1.5 kW. If the hot plate, the pot, and the water are all at 20 oC when the heating element is switched on, how long will it take until the water begins to boil? Neglect heat losses to the surroundings.
