Decide which of the following statements are true and which are
false.
True False Real gas molecules behave most
ideally at low temperature and high pressure.
True False At constant temperature, the
lighter the gas molecules, the smaller the average kinetic
energy.
True False At constant temperature, the
lighter the gas molecules, the smaller the average velocity.
True False In order for two separate 1.0 L
samples of O2(g) and H2(g) to have the same
average velocity, the O2(g) sample must be at a lower
temperature than the H2(g) sample.
True False Ideal gas molecules have small
volumes and exert weak attractive forces on one another.
True False As temperature increases, the
average kinetic energy of a sample of gas molecules increases.
