States of Matter

the state of matter with a definite volume but no definite shape

liquid

the state of matter with no definite volume and no definite shape

gas

states of matter (common)

solid, liquid, and gas

Condensation

Gas to Liquid

Liquid to gas

evaporation

liquid to solid

Freezing

solid to liquid

melting

Freezing causes the molecules to move...

slower & closer together

Matter

Anything that has mass and takes up space.

Evaporation causes the molecules to move...

faster & further apart

Mass

The amount of matter an object is made up of. Measured by a balance.

Volume

The amount of space an object takes up.

Physical Properties

a characteristic that can be observed or measured without changing what the substance is.

Condensation causes the molecules to move...

slower & closer together

How do you describe the particles in a solid?

Strong attraction between particles. Locked tightly together (touching) and vibrate.

How do you describe the particles in a liquid

Low intermolecular attraction between particles(still touching) but allows particle to slide past each other

How would you describe the particles in a gas

Particles moving very fast and freely. No intermolecular attraction.

Condensation (absorbs or releases) heat

releases (loses)

Melting (absorbs or releases) heat

absorbs (gains)

Freezing (absorbs or releases) heat

releases (loses)

Evaporation (absorbs or releases) heat

absorbs (gains)

Solid

have a definite shape and volume
