14 States of Matter There are four states of matter they are Solids: Table, Wall, Chair, Desk, etc.Liquids: Water, Mountain Dew, CokeGases: Carbon Dioxide, Methane, Propane, Natural GasPlasma: Lightning, Stars, Comet Tails, Fireballs made by Nuclear Weapons
2Phase of Matter-SolidSolids: Molecules are packed very close together in a definite structure. These molecules have low energy and high density.
3Phase of Matter-Liquid Liquids: Molecules not as close together, but still have an attraction to each other, no definite structure. Higher energy than solids and medium density. Liquids take the shape of their container.
4Phase of Matter-GasGas: Molecules spaced very far apart from each other, no definite structure. High energy and low density.
5Phase of Matter-Plasma Plasma: Molecules have very high energy, molecules are very hot and have positive or negative charges. Very rare state of matter, stars are made of plasma.
6Phase Changes-Melting Melting: Going from a solid to a liquidExamples: Snowman melting and an ice cube melting in your Mountain Dew making it taste watery.Tim and Moby on Heat
7Phase Change-Evaporation Evaporation: Material goes from a liquid to a gas.Example: Puddle of water forms after it rains but eventually it evaporates into moisture in the air.
8Phases Changes-Sublimation Material goes directly from a solid to a gas and skips the liquid phase.Example: Dry Ice or snow melting on a really warm winter day. You can see steam or water vapor coming up off the snow.
9Phase Changes-Condensation Condensation: Material goes from a gas to a liquid.Examples: Condensation can be left on your bedroom window when it is nice and warm inside but it is cold outside. The same thing happens when you take a shower and the hot steam from the shower hits the cold bathroom mirror.
10Phase Changes-Freezing Freezing: Going from a liquid to a solid.Examples: Putting ice in the freezer. Frozen frost on the ground when you wake up in the morning.
11Phase Changes-Deposition Going directly from a gas to a solid this skips the liquid phase.Example: Water particles in the air being frozen directly onto a car window forming a solid sheet of ice.
13Physical PropertiesA physical property can be observed or measured without changing the matter’s identity.Examples of Physical Properties:Thermal ConductivityState of MatterDensitySolubilityDuctilityMalleability
14Physical ChangeA physical change is a change that affects one or more physical properties of a substance, but do not form new substances.ExamplesPhase Changes (melting, freezing etc.)Erosion of soilSmashing a can
15Chemical PropertiesA chemical property is a property of matter that describes its ability to change into new substances.Examples of Chemical properties:FlammabilityAbility To RustReactivity
16Chemical ChangeA chemical change happens when one or more substances are changed into new substances.Examples of Chemical ChangeChange of odorFormation of GasRustingChange of ColorProduction of HeatFizzingSound or light given offChange in volume of material
