Bell Ringer Get out “States of Matter” flow chart from yesterday

States of Matter & Changes of State

Molecules Solid Has a definite shape and volume Molecules are packed tightly together Molecules only vibrate slightly Molecules are VERY attracted to each other Molecules

Molecules in a glass of water Liquid Has a definite volume but no definite shape (Takes the shape of its container) Molecules are packed almost as tightly as a solid Molecules move freely around each other Molecules are somewhat attracted to each other. Molecules in a glass of water

Gas Molecules in a sealed container No definite shape or volume As gas molecules spread apart, they fill all the available space. (takes on shape of container) Molecules move at high speeds in all directions Molecules not attracted to each other. Gas Molecules in a sealed container

Plasma Molecules in a sealed container No definite shape or volume As plasma molecules spread apart, they fill all the available space. (takes on shape of container) plasma is made by heating a gas until its electrons have enough energy to escape the hold of the nucleus. Plasma Molecules in a sealed container e- e- e-

Changes of States

Solid Solid to Liquid Melting Solid to Gas Sublimation

Liquid Liquid to Solid Freezing Liquid to Gas Evaporation– happens at surface Boiling– happens below surface

Gas Gas to Solid Deposition Gas to Liquid Condensation
