Chapter 3 States of Matter Flashcards
(17 cards)
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
the change of state from a gas to a liquid
condensation
the process in which a solid changes directly into a gas
sublimation
