• Solids, liquids, and plasma

• Gases, liquids, and vapors

• Solids, gases, and aerosols

What does kinetic theory explain?

• The movement of planets

• The arrangement and motion of particles

• The behavior of light

• The formation of clouds

What is density?

• The weight of a substance

• The mass per unit volume of a substance

• The volume of a substance

• The temperature of a substance

Which state of matter has a fixed volume and shape?

• Gas

• Liquid

• Solid

• Plasma

What is boiling?

• When a liquid changes to a gas at a constant temperature

• When a solid changes to a liquid

• When a liquid freezes

• When a gas changes to a liquid

What happens to the forces of attraction when a solid turns to a liquid?

• They disappear completely

• They are overcome or broken

• They remain the same

• They become stronger

What is condensation?

• When a liquid changes into a gas

• When a solid changes into a gas

• When a gas changes into a solid

• When a gas changes into a liquid

What is evaporation?

• When a solid changes into a liquid

• When a liquid freezes

What is the relationship between pressure and volume in a gas?

• As pressure increases, volume increases

• As pressure increases, volume decreases

• Pressure and volume are unrelated

• As pressure decreases, volume decreases

What is diffusion?
