Phases of Matter

Determined by particlearrangement and speed

4 Phases of Matter1. Solid

4 Phases of Matter1. Solid

- have a definite shapeand a definite volume

4 Phases of Matter1. Solid

(particles are tightly packed and move slowly)

4 Phases of Matter2. Liquid

4 Phases of Matter2. Liquid

- have no definite shapeand a definite volume

4 Phases of Matter2. Liquid

(particles are free to move)

4 Phases of Matter3. Gas

4 Phases of Matter3. Gas

- have no definite shapeand no definite volume

4 Phases of Matter3. Gas

(particles are in constant motion)

4 Phases of Matter4. Plasma

4 Phases of Matter4. Plasma

- cannot be contained by ordinary matter

4 Phases of Matter4. Plasma

(VERY HIGH energyex. Sun, lightning)

Phase Changes

The change from one phase of matter to another due to changes in energy

Phase ChangesSOLID – LIQUID:

Phase ChangesSOLID – LIQUID:- Melting (solid to liquid)

Phase ChangesSOLID – LIQUID:- Melting (solid to liquid)

due to an absorption of heat energy

Phase ChangesSOLID – LIQUID:- Freezing (liquid to solid)

Phase ChangesSOLID – LIQUID:- Freezing (liquid to solid)

due to a release of heat energy

Phase ChangesSOLID – LIQUID:- Heat of Fusion

80 cal./g (water)

Phase ChangesLIQUID - GAS:

Phase ChangesLIQUID - GAS:- Vaporization (liquid to gas)

Phase ChangesLIQUID - GAS:- Vaporization (liquid to gas)

due to an absorption of heat energy

Phase ChangesLIQUID - GAS:- Condensation (gas to liquid)

Phase ChangesLIQUID - GAS:- Condensation (gas to liquid)

due to a release of heat energy

Phase ChangesLIQUID - GAS:- Heat of Vaporization

540 cal./g (water)

Phase ChangesSOLID - GAS:

Phase ChangesSOLID - GAS:Sublimation (solid to gas)

Phase ChangesSOLID - GAS:Sublimation (solid to gas)

-due to absorbing heat energy

Gas LawsLaws that describe the

behavior of gasses undercertain conditions

Gas LawsBOYLE’S LAW:Pressure and volume areinversely related (as onegoes up, the other goesdown)

Gas LawsCHARLES’ LAW:Temperature and volume aredirectly related (as onegoes up, the other goes up)
