It’s what the world’s made of.

What do you know about matter?

Do you know the phases of matter?

Solids

Liquids

Gasses

Plasma

Solids hold their own

shape have weight take up space

Liquids

take the shape of their container

have weight take up space

Gasses

spread out to fill the entire space given

have weight take up space

Plasma

Similar to gas, but the particles are electrically charged

Example = lightning Used in fluorescent

light bulbs and Neon lights.

What would it take for matter to move from one state to another?

Energy determines the state!

Particles in Solids: Are packed tightly

together

Have very little energy

Particles in Liquids: Are loosely

packed

Have medium energy levels

Particles in Gasses: Move freely

Have LOTS of energy

Particles in Plasma: Are electrically

charged

Have EXTREMELY high energy levels

Solid + Energy = ?

Liquid + Energy = ?

Physical change When matter changes state No new substance is formed

Examples

Ice cream melted ice cream

Chocolate melted chocolate

Ice water water vapor

Chemical change When new matter is formed

Examples

The metal of an old bike rusting

Jewelry becomes tarnished

Bread becomes toast

Burning paper
