Matter: anything that takes up space and has mass
Mass: is the fundamental property of matter
Macroscopic: refers to properties that can be observed by five human senses
Microscopic: refers to properties that are too small to be seen even with the very best of microscopes
Density: is the ratio of mass per unit volume
Crystals: individual pieces of crystalline solids
Unit cell: is the smallest arrangements of connected points that can be repeated in three directions to form the lattice
Metallic solids: consisting of positive metal ions surrounded by a sea of mobile electrons
Amorphous solid: is one in which the particles are not arranged in a regular or repeating pattern.
Fluidity: is the ability to flow.
Viscosity: a measure of the resistance of a liquid to flow.
Surface tension: is the energy required to increase the surface area of a liquid by a given amount.
Cohesion: is the force of attraction between identical molecules.
Adhesion: is the force of attraction between different molecules.
Plasma: considered as the fourth phase of matter.
Melting: Solid to Liquid
Vaporization: is the process which a liquid changes to gas or vapor.
Vapor pressure: the pressure exerted by the vapor over the liquid.
Condensation: the process by which a gas or a vapor becomes liquid
Freezing: liquid to solid
