Problem- Consider a 1.0-L sample of helium gas and a 1.0-L sample of argon gas, both at room temperature and atmospheric pressure. Answer the following questions:
a) Do the atoms in the helium sample have the same average kinetic energy as the atoms in the argon sample?
b) Do the atoms in the helium sample have the same average velocity as the atoms in the argon sample?
c) Do the argon atoms, because they are more massive, exert a greater pressure on the walls of their container?
