Decide which of the following statements are true and which are false.
1. Real gas molecules behave most ideally at high temperature and low pressure.
2. At constant temperature, the heavier the gas molecules, the larger the average velocity.
3. Ideal gas molecules have small volumes and exert weak attractive forces on one another.
4. 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.
5. As temperature increases, the average kinetic energy of a sample of gas molecules decreases.
6. At constant temperature, the heavier the gas molecules, the smaller the average kinetic energy.
