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 of helium greater than, less than, or equal to 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.
Solids and liquids resist being compressed. They are not totally incompressible, but it takes large forces to compress them even slightly. If it is true that matter consists of atoms, what can you infer about the microscopic nature of solids and liquids from their incompressibility?
The Nobel Prize in Physics was awarded for the discovery of graphene, a two-dimensional form of carbon in which the atoms form a two-dimensional crystal-lattice sheet only one atom thick. Predict the molar specific heat of graphene. Give your answer as a multiple of .
A box contains of nitrogen at . What is the rate of collisions (collisions/s) on one wall of the box?
An experiment you're designing needs a gas with . You recall from your physics class that no individual gas has this value, but it occurs to you that you could produce a gas with by mixing together a monatomic gas and a diatomic gas. What fraction of the molecules need to be monatomic?
