Unit 3 Vocabulary

1. A substance that takes the shape of its container, takes up all the space it’s given (volume changes), and exerts force on the walls of its container.

• Liquid

• Solid

• Gas

• Pressure

1. States that all matter is composed of particles that are in constant, random motion.

• Kinetic Molecular Theory

• Kinetic Energy

• Inelastic collisions

• Intermolecular forces

1. When particles collide, lose kinetic energy to the surrounding environment, and stick to each other due to their strong attraction to one another.

• Elastic collisions

• Solid

• Inelastic collisions

• Aqueous

1. When two liquids are able to homogeneously mix together.

• Liquid

• Solid

• Miscible

• Melting Point

1. When particles collide, transfer kinetic energy, but do not stick to each other due to their weak attraction to one another.

• Elastic collisions

• Solid

• Inelastic collisions

• Aqueous

1. A substance that has a constant shape and volume, strong intermolecular forces, and low vapor pressure.

• Liquid

• Solid

• Gas

• Pressure

1. Having been dissolved in water or able to be dissolved in water. A phase typically reserved for ionic solids due to their high solubility in water.

• Liquid

• Aqueous

• Miscible

• Soluble

1. The process of a substance moving from a gas to a liquid.
