Chapter 3 States of Matter 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 not a definite volume
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 volume or shape
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 three-dimensional space
volume
the amount of force exerted per unit area of a surface
pressure
the law that states that the volume of a gas is 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 to the temperature of a gas when pressure is constant
Charles’s 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
