States of Matter Notes By: Mrs. Nelson

Matter Poem Matter, matter everywhere. There’s matter in your hair. Matter in the air. There’s even matter in a pear! There’s liquid matter, solid matter, and matter that’s a gas. Even you are matter, because you have volume and mass!

Matter Things that have mass and take up space This includes almost everything around us such as air, water, people, and rocks. Matter does not include light, heat, and sound.

Question: According to the definition above, air is a type of matter but light is not. Explain why this is true.

Molecule A molecule is the smallest particle of a substance still considered the substance.

Four States of Matter All matter comes in one of four states: Solid Liquid Gas Plasma

Solid Rigid Boundary/interface Not easily compressed

Solid Lowest energy state Particles packed together tightly in crystal structure Particles vibrating back and forth Particles barely moving

Solid Examples:

Liquid Flows Boundary/Interface Not easily compressed

Liquid Higher energy state than solid Particles not as close as in a solid Particles move freely and “slide”past each other easily Particles move faster than in a solid

Liquid Examples:

Gas (Vapor) Flows No boundary/interface Easily compressed

Gas (Vapor) Highest energy state Particles very far apart Particles moving very freely (bump into each other) Particles move fastest in a gas state Water vapor, oxygen, and helium are examples

Plasma Plasma is a state of matter that we do not often observe naturally on earth or on our sister planets because it requires a great deal of energy.
