Decide which of the following statements are true and which are false. True Real gas molecules have a volume and exert attractive forces on one another. False As temperature increases, the average kinetic energy of a sample of gas molecules decreases. 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 higher temperature than the H2(g) sample. False At constant temperature, the lighter the...

Decide which of the following statements are true and which are false.
Decide which of the following statements are true and which are false. At constant temperature, the lighter the gas molecules, the larger the average kinetic energy. Real gas molecules behave most ideally at low temperature and high pressure. As temperature decreases, the average kinetic energy of a sample of gas molecules increases In order for two separate 1.0 L samples of O2(g) and H2(g) to have the same average velocity, the H2(g) sample must be at a higher temperature than the O2(g) sample At constant...
