TermDefinition
condensing Changing from a gas into a liquid.
conduction When heat is transferred through a substance by passing from one particle to the next.
contraction When a substance takes up less space, because its particles have moved closer together. This happens when a substance is cooled.
convection When heat is transferred by the movement of a heated (less dense) liquid or gas up through a more dense liquid or gas. This causes currents which transfer heat energy through the substance.
density How tightly packed together the particles are in a substance.
diffusion When particles in a liquid or gas move from where they have a high concentration to where they have a low concentration
evaporating Changing from a liquid into a gas.
expansion When a substance takes up more space, because its particles have moved further apart. This happens when a substance is heated.
gas A type of matter in which the particles are far apart. It will fill (or escape) its container.
liquid A type of matter in which the particles can slide past each other. It can be poured and will take the shape of the bottom of its container.
matter A substance that occupies space and has mass.
melting Changing from a solid into a liquid.
particles The very small parts which make up a substance. The movement of these parts and distance between them is what makes the substance a solid, liquid or gas.
solid A type of matter in which the particles are packed tightly together. It cannot be poured, and does not take on the shape of its container.
