solid
the state in which matter has definite shape and volume
liquid
the state in which matter takes the shape of its container and has definite volume
gas
the state in which matter changes in shape and volume
crystalline
the type of solid that has a very orderly, three dimensional arrangement of particles
amorphous
the term that describes the type of solid that is made of particles that are in no special order
plasma
the state of matter that does not have a definite shape or volume and whose particles have
broken apart
melting
the change of state from a solid to a liquid
freezing
the change of state from a liquid to a solid
condensation
the change in state from a gas to a liquid
vaporization
the change in state from a liquid to a gas; includes boiling and evaporation
Boyle's Law
at a constant temperature, the volume of the gas increases as its pressure decreases
Charles' Law
the volume of a gas increases as its temperature increases
endothermic
a physical or chemical change in which energy is absorbed
evaporation
vaporatization that occurs at the surface of a liquid below its boiling point
exothermic
physical or chemical change in which energy is given off
boiling
vaporization that occurs throughout a liquid
states of matter
the physical forms in which a substance can exist
pressure
the amount of force exerted on a given area
viscosity
a liquid's resistance to flow
change of state
the change of a substance from one physical form to another
sublimation
change of state from a solid directly to a gas
solid, liquid, gas and plasma
states of matter
2 types of solids
amorphous and crystalline
solid
particles are very close
solid
attraction between particles is very strong
amorphous
BB's poured into a jar
liquid
less attraction between the particles
liquid
particles move fast to overcome some attraction
liquid
particles SLIDE past each other
if it pours more slowly, it has a higher
vicosity
honey has a higher viscosity than
water
gas
particles mover very quickly so they can break away from each other
gas
empty space between the particles
as volume of the gas decreases
the pressure increases
volume of the gas decreases
temperature decreases
plasma
state of matter whose particles have broken apart
plasma
very high energy
plasma
conducts electricity
gas
does not conduct electricity
lightening, fire and auror borealis
plasma
fluorescent lights caused by passing electricity thru gases
plasma
air pressure
lower at higher altitudes
air pressure is lower at higher altitudes so
the volume of gas in the balloon increases
overfilled balloons at high altitudes
pop
as the volume of the gas decreases
answer
Boys Visit Intelligent Puppy Dogs
Boyles: Volumen increases pressure decreases
Cleaning Vomit is Too Icky!
Volume increases as temperature decreases
amorphous
particles don't line up neatly but are very close
particles in neat rows and columns
crystalline
surface tension
force that acts on the surface of a liquid
surface tension
causes liquid to form spherical drops
pressure
the amount of force exerted on a given area
more force
more pressure
basketball has more pressure than a
beachball
boiling and evaporations are
vaporization
change of state
the chane from one physical form to another
boiling point
the temp at which a liquid boils and becomes a gas
freezing point
the temperature at which a liquid changes into a solid
melting point
the temperature at whcih a substances changes from a solid to a liquid
condensation point
the temperature at which a gas becomes a liquid
