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.
