Chapter 2 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 no 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 shape or volume.
Gas
A measure of how hot ( or cold) something is; specifically, a measure of the movement of particles.
Temperature
A measure of the size of a body, or region in 3D space.
Volume
The amount of force exerted per unit area of a surface
Pressure
The law that states that the volume of a gas 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 is constant.
Charles’ 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 energy
Melting
The change of a substance from 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
