Unformatted text preview: Physics 7B: MT1 Review Session by Peter Battaglino February 23, 2007 Problem 1: An object leaving the surface of the Earth will escape its gravitational attrac- tion and embark upon an eternal journey into outer space if its speed exceeds 1 . 12 10 4 m / s (Bonus: show this!). (a) At what temperature is the rms speed of Oxygen molecules sufficient to leave the surface of the Earth? (b) How about for Helium? (c) Can you explain why our atmosphere contains Oxygen but not Helium? Problem 2: How much space (in gallons) must you leave in your cars thirteen-gallon steel gasoline tank when youre filling it up at 0 C, if you plan on driving it in 40 C weather? The coefficient of linear expansion for steel is 12 10- 6 C- 1 and the coefficient of volume expansion for gasoline is 950 10- 6 C- 1 . Problem 3: An insulated cylindrical piston is filled with 2 moles of a monatomic gas at initial temperature 300K, and is maintained at one atmosphere. A second insulated containerinitial temperature 300K, and is maintained at one atmosphere....
