solid
state of matter with definite shape and definite volume
liquid
state of matter with NO definite shape but has a definite volume
gas
state of matter with NO definite shape and NO definite volume
plasma
gas-like state of matter consisting of a mixture of free electrons and atoms that are stripped of their electrons
physical attractions
attraction between particles that wants them to STICK together
sun
well known star that consists of plasma gas
lightning
produces plasma gas
fluorescent lights
glows when mercury gas forms into a plasma state
aurora borealis
occur when highly charged electrons from the solar wind interact with elements in the earth's atmosphere forming a plasma state.
melting
the change in state from a solid to a liquid
freezing
the change in state from a liquid to a solid
evaporating/evaporation
the process that occurs when VAPORIZATION takes place ONLY at the SURFACE;(change in state from liquid to gas at surface)
boiling
the process that occurs when VAPORIZATION takes place INSIDE a liquid as well as on the SURFACE; (change in state from liquid to gas throughout the liquid)
condensing/condensation
change in state from a gas to a liquid
sublimating/sublimation
change in state from a SOLID directly to a GAS without passing through the liquid state (and vice versa)
vaporizing/vaporization
change in state form a liquid to a gas (can describe either evaporating or boiling)
boiling point
the temperature in which a liquid becomes a gas
melting point
the temperature in which a solid becomes a liquid
kinetic theory
everything is made of moving particles
matter
anything that has mass and takes up space (volume)
crystalline
solids that are made up of crystals
amorphous
solid particles that are not arranged in a regular pattern; it may become softer and softer
surface tension
is the result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together;acts like sort of skin on the surface
