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)
