QQ: Make a table with 3 columns labeled: solid, liquid, and gas QQ: Make a table with 3 columns labeled: solid, liquid, and gas. Write the statements below in one or more of the 3 columns. My particles move. I have no definite volume or shape. 3) My particles move the slowest. 4) I have the most energy 5) I have definite shape and volume. 6) I take the shape of my container. 7) I have a definite volume but not definite shape.

Today’s Objective: I can use a phase change graph to describe how matter changes.

So What's So Special About Oobleck?

Phase Change: Going from one state of matter to another Caused by change in energy

Phase Changes are Physical Changes. They are reversible. Chemical Reactions are not. Gas Liquid Solid

* The substance is warmer (heat was absorbed by it) * The surroundings are cooler (heat left for the substance)

Exothermic: The energy “exits” the substance The substance is cooler (the heat left it) * The surroundings are warmer (that’s where the heat went)

Gas Condensation Melting Solid Liquid Freezing

Phase change from gas to liquid Condensation: Phase change from gas to liquid Exothermic: Heat leaves the water

Gas Condensation Vaporization Melting Solid Liquid Freezing

Vaporization: * Change from liquid to gas * Endothermic (system absorbs the heat energy to change) Boiling Evaporation: at surface & below boiling point

Gas Sublimation Solid Liquid Condensation Vaporization Melting Freezing

(never becomes a liquid) Sublimation: Phase change from solid to gas (never becomes a liquid) Endothermic: Heat enters system

Gas Deposition Solid Liquid Condensation Vaporization Sublimation Melting Solid Liquid Freezing

(never becomes a liquid) Deposition: phase change from gas to solid (never becomes a liquid) Exothermic: Heat leaves the vapor

What happens to the temperature here? Temperature is constant during phase change.
