Matter Glossary
Atom the building blocks of all matter
Boiling change of state from liquid to gas
Boiling point the temperature at which a liquid turns into a gas
Condensation change of state from gas to liquid
Conduction the flow of heat or electricity through a substance
Conductor a substance that allows heat or electricity to move through it easily
Contraction when the distances between solid, liquid or gaseous particles decrease; the particles come closer together.
Density the mass of a substance per unit volume
Diffusion the movement of gas or liquid particles from an area of high concentration to an area of low concentration until the concentration is equal
Energy the ability to do work
Evaporation change of state from liquid to gas
Expansion when the distances between solid, liquid or gaseous particles increases; the particles spread out.
Forces pushes or pulls
Freezing change of state from liquid to solid
Insulator a substance that does not allow heat or electricity to flow through it easily
Mass the amount of matter in an object; measured in kilograms (kg) or grams (g)
Matter a substance that has mass and occupies space
Melting change of state from solid to liquid
Melting point the temperature at which a solid turns into a liquid
Particles matter which is too small to be seen
Solidify to freeze; change of state from liquid to solid
States solid, liquid and gas; a substance can exist in any of these 3 states.
Sublimation change of state from a solid to gas without first forming a liquid e.g. dry ice
Volume the amount of space occupied by matter
