States of MatterSolids, liquids and gases are the three states of
matter. All matter is made from small particles.
These particles are called atoms and molecules.

Solids
Solids have a definite shape and volume.
The particles of a solid are arranged in a tight, regular pattern, and move very little.
Particles are so close to one another that they only vibrate.

Types of SolidsAmorphous Crystalline
NOT arranged in a particular pattern
DOES NOT melt at specific temperatures. It just becomes softer and changes into other substances.
Examples: plastics, rubber, glass
Solids that are made of crystals
Regular, repeating patternMelts at a specific
temperature
Examples: salt, sugar, snow

LiquidsLiquids take on the shape of the
container they are in– no definite
shape.
Liquids have a definite volume
Particles of a liquid move freely
around one another
Fluid: “a substance that flows”

Properties of LiquidsSurface tension: result of an inward pull
among the molecules of a liquid that brings the molecules on the surface closer together

Properties of LiquidsViscosity: a liquid’s resistance to flow
HIGH viscosity: flows slowly
LOW viscosity: flows quickly

Your turn!
Low viscosity High viscosity

GasMolecules are widely separated,
move around freely, and move at high speeds.
Gases do not have a definite shape
Gases also do not have a definite volume because they can be compressed (squashed into a smaller volume).

Solid Liquid Gas

CORRECT
There are three different states of matter:
solid, liquid, and gas.

Correct Again!!
Atoms in a gas are actually farther apart than the
atoms in a liquid.
Gases are the least dense and have atoms that are
the most spread out.

Geeze, you are extremely smart!!Solids have the least energetic molecules.
