The physical forms of matter which include solid, liquid, and gas.
States of Matter
The state of matter in which the volume and shape of a substance is fixed.
Solid
The state of matter that has a definite volume but not a definite shape.
Liquid
The force that acts on the surface of a liquid and that tends to minimize the area of the surface.
Surface Tension
The resistance of a gas or liquid to flow.
Viscosity
A form of matter that does not have a definite volume or shape.
Gas
A measure of how hot(or cold) something is; specifically, a measure of the movement of particles.
Temperature
A measure of the size of a body or region in three-dimensional space.
Volume
The amount of force exerted per unit area of a surface.
Pressure
The law that states that the volume of a gas is inversely proportional to the pressure of a gas when pressure is constant.
Boyle’s Law
The law that states that the volume of a gas is directly proportional to the temperature of a gas when pressure is constant.
Charles’s Law
The change of a substance from one physical state to another.
Change Of State
The change of state in which a solid becomes a liquid by adding energy.
Melting
The change of a substance from a liquid to a gas.
Evaporation
The conversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure.
Boling
