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
|
|
|
tepmerature
|
a measure of how hot (or cold)something is; specifically, a measure of the movement of the particles

|
the law that states that the volume of gas is inversely proportional to the pressure of a gas when the temperature is constant
|
|
|
Charle's law
|
the law that states that the volume of 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
|
|
|
melting
|
the change of state in which a solid becomes a liquid by adding energy
