Decide which of the following statements are true and which arefalse.
1. Real gas molecules behave most ideally at high temperatureand low pressure.
2. At constant temperature, the heavier the gas molecules, thelarger the average velocity.
3. Ideal gas molecules have small volumes and exert weakattractive forces on one another.
4. In order for two separate 1.0 L samples of O2(g) and H2(g) tohave the same average velocity, the O2(g) sample must be at a lowertemperature than the H2(g) sample.
5. As temperature increases, the average kinetic energy of asample of gas molecules decreases.
6. At constant temperature, the heavier the gas molecules, thesmaller the average kinetic energy.
