Matter
Anything that has mass and volume
Mass
Quantity of matter, a substance, or object contains
Volume
Amount of space taken up by a substance or objects
Fixed mass
Solid, Liquid, Gas
Fixed Volume
Solid, Liquid
Fixed Shape
Solid
Particles are..
always moving
attracted to one another
too small to see
spaces between them varies depending on state
Kinetic Energy
energy due to motion
Kinetic Molecular Theory
All matter is made of very small particles
there is empty space between particles
Particles are constantly moving. Particles are colliding with each other and the walls of their container
energy makes particles move, the more energy the particles have, the faster they have the further apart they get.
Solid
Particles are tightly packed, so they cannon move freely. they can only vibrate
Liquid
particles are farther apart. they can move by sliding by each other
Gas
particles are very far apart and move around quickly
Thermal Expansion
increase in volume of a substance when its temperature is raised
Thermal Contraction
decrease in volume of a substance when its temperature is lowered
Thermal Energy
total kinetic energy of all the particles in the substance
Heat
transfer of thermal energy between two material of different temperature. High-Low
Temperature
average kinetic energy of the particles in a substance
Melting
Solid to Liquid
Evaporation
Liquid to Gas
Condensation
Gas to Liquid
Solidification
Liquid to Solid
Sublimation
Solid to Gas
Deposition
Gas to Solid
Melting Point
Temperature at which solid turns to liquid
Boiling Point
Temperature at which liquid turns into gas

Charles Law
as the temperature of gas increases at a constant pressure, its volume increases. when the temperature of a gas decreases at a constant pressure, its volume decreases.
