According to the kinetic theory of gases, what is the relationship between temperature and kinetic energy of gas particles?

Temperature has no impact on the kinetic energy of gas particles.

Temperature directly correlates with the average kinetic energy of gas particles. (correct)

Temperature increases the volume of gas particles.

Higher temperature decreases the kinetic energy of gas particles.

What characterizes ideal gas behavior?

Ideal gases exhibit intermolecular forces between particles.

All particles in an ideal gas move at different speeds.

Ideal gases move at different speeds at lower temperatures.

All particles in an ideal gas move at the same speed. (correct)

In the kinetic theory of gases, why are gas particles considered point masses?

To increase their kinetic energy.

To allow them to move freely without significant influence from their volume. (correct)
