Question

Decide which of the following statements are true and which are false.

As temperature increases, the average kinetic energy of a sample of gas molecules decreases.
Ideal gas molecules have small volumes and exert weak attractive forces on one another.
At constant temperature, the lighter the gas molecules, the smaller the average velocity.
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.
Real gas molecules behave most ideally at high temperature and low pressure.
At constant temperature, the lighter the gas molecules, the smaller the average kinetic energy.
