By Connie Schaef

Open Ended

Consider a 1.0 L sample of helium gas and a 1.0 L sample of argon gas, both a room temperature and atmospheric pressure.

Do the atoms in the helium sample have the same average kinetic energy as the atoms in the argon sample?

Open Ended

Consider a 1.0 L sample of helium gas and a 1.0 L sample of argon gas, both a room temperature and atmospheric pressure.

Do the atoms in the helium sample have the same average velocity as the atoms in the argon sample?

Open Ended

Consider a 1.0 L sample of helium gas and a 1.0 L sample of argon gas, both a room temperature and atmospheric pressure.

Do the argon atoms, because they are more massive, exert a greater pressure on the walls of the container? Explain.

Calculate the mean square root velocity and kinetic energy of F₂, Cl₂, and Br₂ at 298 K. Rank these three halogens with respect to their rate of effusion.

Open Ended

A sample of N₂O effuses from a container in 42 seconds. How long will it take the same amount of gaseous I₂ to effuse from the same container under identical conditions.

Open Ended

Use the van der Waals equation and the ideal gas equation to calculate the volume of 1000 mol of neon at a pressure of 500.0 atm and a temperature of 355.0 K. Explain why the two values are different.
