Question: (a) The density of water at 0ºC is very nearly(it is actually), whereas the density of ice at 0ºC is. Calculate the pressure necessary to keep ice from expanding when it freezes, neglecting the effect such a large pressure would have on the freezing temperature. (This problem gives you only an indication of how large the forces associated with freezing water might be.) (b) What are the implications of this result for biological cells that are frozen?

A bicycle tire has a pressure of 7.00×105N/m2at a temperature of 18.00Cand contains2.00L of gas. What will its pressure be if you let out an amount of air that has a volume of100cm3 at atmospheric pressure? Assume tire temperature and volume remain constant.

高压气瓶包含50.0 lof毒素c gas at a pressure of 1.40×107N/m2 and a temperature of 25.00C. Its valve leaks after the cylinder is dropped. The cylinder is cooled to dry ice temperature (-78.50C) to reduce the leak rate and pressure so that it can be safely repaired. (a) What is the final pressure in the tank, assuming a negligible amount of gas leaks while being cooled and that there is no phase change? (b) What is the final pressure if one-tenth of the gas escapes? (c) To what temperature must the tank be cooled to reduce the pressure to1.00atm (assuming the gas does not change phase and that there is no leakage during cooling)? (d) Does cooling the tank appear to be a practical solution?

Question:(a) An automobile mechanic claims that an aluminum rod fits loosely into its hole on an aluminum engine block because the engine is hot and the rod is cold. If the hole is 10.0% bigger in diameter than the 22.0ºC rod, at what temperature will the rod be the same size as the hole? (b) What is unreasonable about this temperature? (c) Which premise is responsible?

Question: One method of getting a tight fit, say of a metal peg in a hole in a metal block, is to manufacture the peg slightly larger than the hole. The peg is then inserted when at a different temperature than the block. Should the block be hotter or colder than the peg during insertion? Explain your answer.
