1. The shore of the ocean is very rocky at a particular place. The rocks form a cave sloping upward from an underwater opening, as shown in Figure 1. Inside the cave is a pocket of trapped air. As the level of the ocean rises and falls with tides, will the level of water in the cave rise and fall? If so, will it have the same amplitude as that of the ocean? Trapped air Water Rock Ocean level at low tide Figure 1 2. A constant-volume gas thermometer is calibrated in dry ice (that is, carbon dioxide in the solid state, which has a temperature of -80.0C) and in boiling ethyl alcohol (78.0 C). The two pressures are 0.900 atm and 1.635 atm. (a) what Celsius value of absolute zero does the calibration yield? (b) What is the pressure at the freezing point of water? 3. A brass ring of diameter 10.00 cm at 20.0 C is heated and slipped over an aluminum rod of diameter 10.01 cm at 20.0C. Assuming the average coefficients of linear expansion are constant, (a) to what temperature must this combination be cooled to separate them? Is this attainable? (b) What if the aluminum rod were 10.02 cm in diameter? 4. Just 9.00 g of water is placed in a 2.00-L pressure cooker and heated to 500.0C. What is the pressure inside the container? 5.
