Science changes of state Flashcards
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 are 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 shaoe
Gas
A measure of how hot (or cold) Something is; Specifically, a measure of the movement of particles
Tempature
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 temperature 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 energu
Melting
The change of a substance to 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
Boiling
