Chapter 2 States of Matter Flashcards
physical forms of matter, which include solid, liquid, or gas
states of matter
the state of matter in which the volume and shape are fixed
solid
the state of matter that has a definite volume, but not a definite shape
liquid
the force that acts on the surface of a liquid 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
matter is made up of tiny particles called
atoms and molecules
solids that have particles that are arranged in an orderly, 3 dimensional arrangement
crystalline
solids that have particles that are not arranged in any special arrangement
amphorphous
the measure of how hot or cold a substance is; specifically, a measure of the average kinetic energy of the particles in an object
temperature
a measure of the size of a body or region in 3-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 proportional to the pressure of a to the pressure of a gas when the temperature is constant
Boyle’s law
the law that states that the the volume of a gas is directly proportional to the temperature of a gas when its pressure is constant
Charles’s law
the change of a substance from of physical form to another
change of state
the change of state when a solid become a liquid by adding heat
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 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
the temperature at which a substance changes from a solid to a liquid
melting point
melting is an (blank) change
endothermic
the change of state from a liquid to a solid
freezing
the temperature at which a liquid changes into a solid
freezing point
