states of matter
the physical forms of matter which include solid, liquid, and gas.
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 a definite shape
surface tension
the force that acts on the surface of a liquid and that tends to minimize the area of the surface.
viscosity
the resistance of a gas or liquid to flow
gas
a form of matter that does not have a definite volume or shape
temperature
a measure of how hot or cold something is
pressure
the amount of force exerted per unit area of a surface
volume
a measure of the size of a body or region in 3-D
melting
the change of state in which a solid becomes a liquid by adding energy
Boyle’s Law
the law that states 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
Change of State
the change of a substance from one physical state to another
Evaporation
the change of a substance from a liquid to a 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
