Particle Theory

anything that takes up space and has mass matter
all matter is made up of particles
the particles of matter are always moving
between particles, there is space
particles are ___________ to one another attracted
the energy an object has due to its motion is this kind of energy kinetic
this is a measure of the average kinetic energy of something's particles temperature
the form of matter with a fixed shape solid
this form of matter has no shape, but has a certain volume liquid
this form of matter has no shape or certain volume gas
the two-word term that means the volume of something increases when the temperature increases thermal expansion
the two-word term that describes how the volume of something shrinks when it cools thermal contraction
the three-word phrase that describes the change from any state of matter to another change of state
the change from solid to liquid melting
the change from liquid to solid freezing
the change from liquid to gas evaporation
the change from gas to liquid condensation
the change from solid to gas sublimation
the change from gas to solid deposition
the temperature at which something changes from a solid to a liquid is called its melting point
the temperature at which something changes from a liquid to a gas is called its boiling point
this is a graph or plot of temperature vs time heating curve
