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 liqued 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
|
|
|

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
