# Question

In deep space the number density of particles can be one particle per cubic meter. Using the average temperature of 3.00 K and assuming the particle is H2 with a diameter of 0.200 nm,

(a) Determine the mean free path of the particle and the average time between collisions.

(b) What If? Repeat part (a) assuming a density of one particle per cubic centimeter.

Show that the mean free path for the molecules of an ideal gas isTwenty particles, each of mass m and confined to a volume V, have various speeds: two have speed v; three have speed 2v; five have speed 3v; four have speed 4v; three have speed 5v; two have speed 6v ; one has speed 7v. Find ...The compressibility / of a substance is defined as the fractional change in volume of that substance for a given change in pressure:A sample of monatomic ideal gas occupies 5.00 L at atmospheric pressure and 300 K (point A in Figure P21.67). It is heated at constant volume to 3.00 atm (point B). Then it is allowed to expand isothermally to 1.00 atm ...A liquid partially fills a container. Explain why the temperature of the liquid decreases if the container is then partially evacuated. (Using this technique, it is possible to freeze water at temperatures above 0°C.)Post your question
