KINETIC MOLECULAR THEORY

The pressure resulting from the collision of air molecules with objects is called

• Kinetic energy

• Atmospheric pressure

• Vapour pressure

• Sublimation

The pressure above a liquid in a sealed container caused by the collision of vaporized particles with the walls of their container is called

• Kinetic energy

• Atmospheric pressure

• Vapour pressure

• Sublimation

Which of the following statements does not agree with the kinetic theory of gases?

• Gas particles move in predictable patterns.

• Gas particles move independently of one another.

• Gas particles are spaced far apart from each other.

• Gas particles are in constant motion.

The average kinetic energy of the particles in a substance is

• Increased as the temperature of the substance increases.

• Unaffected by changes in the temperature of the substance.

• Increased as the temperature of the substance decreases.

• Equal to the total thermal energy absorbed by the substance.

What happens to the kinetic energy of the particles in a sample of gas as the temperature of the sample increases?

• It increases, then decreases

• It does not change

• It increases

• It decreases
