Forms of Matter

solid

The particles are tightly packed.

The particles do not move around.

liquid

The particles are close together.

The particles vibrate, move, and slide past each other.

gas

The particles are very separated.

The particle vibrate and move quickly.

condensation

Gas to liquid:

(Dew on grass)

evaporation

Liquid to Gas:

(Puddles disappearing)

melting point

Solid to liquid:

(Ice to water)

freezing point

Liquid to solid:

(Water to ice)

Liquid

can be poured and take on the shape of their container. Has mass and volume.

Evaporation

the change of a liquid to a gas

gas

A state of matter that has no definite shape or volume. Has a high kinetic energy.

condensation

A change of state from a gas to a liquid due to a cooling or compression.

Matter

anything that takes up space and has mass

Particles

Tiny atoms that make up all matter

atoms

basic particle from which all elements are made

element

cannot be broken down into any other substance

molecule

2 or more atoms bonded (same or different)

compound

2 or more different atoms bonded together in a set ratio

mixture

2 or more substances mixed together but NOT chemically bonded

homgeneous mixture

mixture in which substances are evenly distributed (you cannot see the different parts)

heterogeneous mixture

mixture in which you can see the different parts

matter

anything that has mass and takes up space
