Viscosity- a measure of the resistance of a liquid to flow, which is affected by the size and shape of particles, and generally increases as the temperature decreases and as intermolecular forces increase. Surface tension- the energy required to increase the surface area of a liquid by a given amount; results from an uneven distribution of attractive forces. Surfactant- A compound, such as soap, that lowers the surface tensions of water by disrupting hydrogen bonds between water molecules; also called a surface active agent.

Crystalline solid- A solid whose atoms, ions, or molecules are arranged in an orderly, geometric, three- dimensional structure; can be classified by shape and by composition. Amorphous solid- a solid in which particles are not arranged in a regular, repeating pattern that often is formed when molten material cools too quickly to form crystals. Covalent solid- A solid, such as diamond, in which every atom is covalently bound to its nearest neighbors to form an extended array of atoms rather than individual molecules.

Vaporization- the energy-requiring process by which a liquid changes to a gas or vapor. Evaporation- the process in which vaporization occurs only at the surface of a liquid.
