QuestionAnswer
State of Matter The physical form in which a substance can exist
Solid The 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 definite shape
Gas A form of matter that does not have a definite volume or shape
Atom Smallest unit of an element that maintains the properties of that element
Surface Tension A force that acts on the particles at the surface of a liquid and tends to minimize the surface
Viscosity The resistance of a gas or liquid to flow
Temperature A measure of how hot (or cold) something is; specifically, a measure of the movement of particles
Volume The amount of space that an object takes up (the measure of the size of a body or region in three-dimensional space)
Pressure The amount of force exerted per unit area of a surface
Boyle's Law For a fixed amount of gas at a constant temperature the volume of the gas is inversely related to pressure (ex: gas increases, volume decreases by the same amount)
Charles's Law For a fixed amount of gas at a constant pressure, the volume of the gas changes in the same way that the temperature of the gas changes (ex; temperature increase and volume of gas increase by the same amount)
A Change in State The change of a substance from one physical form to another. Identity of the substance doesn't change.
Melting The change of state from a solid to a liquid by adding energy
Endothermic Energy is added (gained) to the substance as it changes state
Freezing The change of state from a liquid to a solid
Exothermic Energy is removed from the substance as it changes state
Evaporation The change of a substance from a liquid to a gas
Boiling The change of state from a liquid to a vapor or gas (when the vapor pressure of the liquid equals the atmospheric pressure)
Condensation The change of state from a gas to a liquid
Sublimation The change of state from a solid to a gas (ex: Dry ice changes directly from a solid to a gas)
Convection Transfer heat from hot to cold in a cycle (Ex. Boiling Water)
Conduction Transfers heat from the source through material
Radiation Transfer of heat by using waves
Melting Point The temperature at which a substance changes from a solid to a liquid.
