Get started for freeFor a monatomic gas, what is the ratio of the volume per atom to the volume of an atom when the mean free path is ten times the atomic diameter?
During a physics experiment, helium gas is cooled to a temperature of at a pressure of What are (a) the mean free path in the gas, (b) the rms speed of the atoms, and (c) the average energy per atom?
Gases, in contrast with solids and liquids, are very compressible. What can you infer from this observation about the microscopic nature of gases?
The two containers of gas in FIGURE Q20.8 are in good thermal
contact with each other but well insulated from the environment. They
have been in contact for a long time and are in thermal equilibrium.
a. Is vrms of helium greater than, less than, or equal to vrms of
argon? Explain.
b. Does the helium have more thermal energy, less thermal
energy, or the same amount of thermal energy as the argon?
Explain.
Two containers hold several balls. Once a second, one of the balls is chosen at random and switched to the other container. After a long time has passed, you record the number of balls in each container every second. In , you find times when all the balls were in one container (either one) and the other container was empty.
a. How many balls are there?
b. What is the most likely number of balls to be found in one of the containers?
