Final Review

The kinetic molecular theory describes the behavior of matter in terms of particles in motion.

• true

• false

An elastic collision occurs when two colliding particles both lose some their kinetic energy.

• true

• false

Temperature is defined as the average kinetic energy of the particles in a sample of matter.

• true

• false

Gases tend to have lower densities than solids because gases have lower molar masses.

• true

• false

A gas with a high molar mass will effuse faster than a gas with a low molar mass.

• true

• false

Helium will effuse faster than xenon

• true

• false

Forces that act between two molecules are referred to as intermolecular forces.

• true

• false

Hydrogen bonds can form between hydrogen and any non-metal.

• true

• false

At the SAME temperature, a gas would have MORE kinetic energy than a Liquid.

• true

• false

Both gases and liquids can be classified as fluids because of their ability to flow.

• true

• false
