Section 2 Flashcards
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 substance.
Viscosity
The resistance of a gas or liquid to flow
Gas
A form of matter that does not have a definate volume or shape
Temperature
A measure of how hot (or cold) something is; specifically, a measure of the movement of particles
Volume
A 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
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.
Melting
The change of state in which a solid becomes a liquid by adding energy
Evaporation
The change of a substance from a liquid to a gas
Boiling
The conversation of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure
