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

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

Explain why the container of water must be inverted when a gas is collected by displacement of water.

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

What is the molar mass of a gas that takes three times longer to effuse than helium?

Explain what determines a substance's state at a given temperature.

Air is a mixture of gases. By percentage, it is roughly 78 percent nitrogen, 21 percent oxygen, and 1 percent argon. (There are trace amounts of many other gases in air.) if the atmospheric pressure is 760 mmHg, what are the partial pressure of nitrogen, oxygen, and argon in the atmospheric?
