States of Matter | Physical forms of matter; solid, liquid, and gas. |
Solid | State of matter in which the volume and shape of a substance are fixed |
Liquid | The state of matter that has a definite volume but not a definite shape. |
Viscosity | The resistance to flow |
Gas | A form of matter that doesn’t have a definite volume of shape. |
Surface Tension | The force that acts on the surface of a liquid and that tends to minimize the area of the surface |
Temperature | A measure of how hot or cold something is (a measure of the movement of particles) |
Volume | A measure of the size of a body or region in 3D space. |
Pressure | The amount of force exerted per unit area of a surface. |
Boyle’s Law | The law that the volume of a gas is inversely proportional to the pressure of a gas when temperature is constant. |
Charles’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. |
Melting | The change of state in which a solid becomes a liquid by adding energy. |
Evaporation | The change of a substance from liquid to gas |
Boiling | The conversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure. |
Condensation | The change of state from a gas to a liquid. |
Sublimation | The process in which a solid changes directly into a gas. |
