Chapter 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 define volume but not a definable shape
surface tension
the force acts on the surface of a liquid and 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 definitesize or shape
volume
a measure of the size of a body or region in three-dimension space
pressure
the amount of force execrated per unit area of a
Boyles 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 Law
the law
Change of State
the change of a substance from one 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 solid
Boiling
the conversion of a liquid to a vapor when the vapor pressure of the liquid equals the amospheric pressure
Condensation
the change of state from a solid to a liquid
