A state of matter that has a definite volume and a definite shape.
A substance that is made up of crystals in which particles are arranged in a regular, repeating pattern.
A solid made up of particles that are not arranged in a regular pattern.
A state of matter that has no definite shape but has a definite volume.
Any substance that can flow.
The resistance of a liquid to flowing.
A state of matter with no definite shape or volume.
A measure of the average energy of the particles of a substance.
The force pushing on a surface divided by the area of that surface.

A form of energy that comes from chemical bonds.
Law of Conservation of Energy
The principle that the total amount of energy remains the same during physical or chemical change.
The change in state from a solid to a liquid.
The change in state from a liquid to a solid.
The change of state from a liquid to a gas.
The process that occurs when vaporization takes place only on the surface of a liquid.
The process that occurs when vaporization takes place inside a liquid as well as on the surface.
The change of state from a gas to a liquid.
The change in state from a solid directly to a gas without passing through the liquid state.
A process in which substances undergo chemical changes, formatting new substances with different properties.
