Consider a gas of N non-interacting molecules enclosed in a container of volume V0. Focus attention on any sub volume V of this container and denote by N the number of molecules located within this sub volume. Each molecule is equally likely to be located anywhere within the container; hence the probability that a given molecule is located within the subvolume V is simply equal to V/V0 a) What is the mean number ¯N of molecules located within V? Express your answer in terms of N0, V0 and V. (b) Find the relative dispersion in the number molecule located within V. Express in terms of ¯N, V and V0
¯¯¯¯
( ¯N-N/ N¯ )^2/N¯
(c) What does the answer to part (b) become when V< (d)What value should the dispersion ¯¯¯¯
( ¯N-N/ N¯ ) assume when V > V0 ? Does the answer to part (b) agree with this expectation

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
