### 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

Solid, Liquid

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

### 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.
