Consider a thin-walled, ﬁ xed-volume container of volume V that holds an ideal gas at constant temperature T. It can be shown by dimensional analysis that the number of particles striking the walls of the container per unit area per unit time is given by nv-/4, where as usual n is the particle number density. The container has a small hole of area A in its surface through which the gas can leak slowly. Assume that A is much less than the surface area of the container. (a) Assuming that the pressure inside the container is much greater than the outside pressure (so that no gas will leak from the outside back in), estimate the time it will take for the pressure inside to drop to half the initial value. Your answer should contain A, V, and the mean molecular speed v-. (b) Obtain a numerical result for a spherical container with a diameter of 40 cm containing air at 293 K, if there is a circular hole of diameter 1.0 mm in the surface.
Explain why the viscosity of a liquid decreases with temperature—that is, how might increased temperature reduce the effects of cohesive forces in a liquid? Also explain why the viscosity of a gas increases with temperature—that is, how does increased gas temperature create more collisions between atoms and molecules?

The hot water coming out of a hydrothermal vent is sometimes called vent fluid. Why would you and I find these vent fluids to be an unpleasant thing to be exposed to? a They are some of the coldest fluids on Earth, being much colder than the normal freezing point of water. b They can be up to 400 degrees Celsius, and contain dissolved compounds like hydrogen sulfide, carbon dioxide, and methane. c The vent fluids are actually an exotic type of magma, made of silicate minerals. d They are actually ultra-pure water, with nothing at all dissolved in them; so pure that even simple cells will die due to the lack of nutrients in the fluids.
