Homework Assignment: (to be completed by Friday 12/14/2012) 1) The viscosity of a gas increases with temperature, yet, the viscosity of a liquid decreases with temperature. Explain. 2) If 2.0x1023 argon atoms strike 4.0 cm2 of wall per second at 90o angle to the wall when moving at 45,000 cm/s, what pressure do they exert on the wall? 3) The speeds of 12 particles in cm/s are: 0.5, 1.5, 1.8, 1.8, 1.8, 1.8, 2.0, 2.5, 2.5, 3.0, 3.5 and 4.0. Find a) the average speed, b) the root- mean- squared speed, and c) the most probable speed of these particles. Explain your resu...
