Infer whether or not temperature has any effect on the diffusion rate of a gas. Explain your answer.

Suppose two gasses in a container have a total pressure of 1.20 atm. What is the pressure of Gas B if the partial pressure of Gas is 0.75 atm?

Describe how the mass of a gas particle affects its rate of effusion and diffusion.

Describe the following concepts as they relate to the behaviors of gases by completing the passages below. $\mathbf{low \ density}$-Gases have low density (____ per ________), in comparison to ____. The difference in density is partly due to the mass of the _____ and also because there is a great deal of ____ between gas particles. $\mathbf{compression \ and \ expansion}$-The large amount of ______ between gas particles allows them to be ________, or pushed, into a ____ volume. Once the pressure is _______, the particles _____ to the original _____. $\mathbf{diffusion \ and \ effusion}$-Because there are no _____ forces of ____ between gas particles, gases _____ past one another. This ____ motion allows gases to mix until they are _______. The movement of ______ past one another is called ____. The process of allowing a gas to escape from a more concentrated container is called _____.
