States of MatterE Q: Describe the particle arrangement in Solids, liquids and gases?SPS5. Students will compare and contrast the phases of matter as they relate to atomic and molecular motion. a. Compare and contrast the atomic/molecular motion of solids, liquids, gases and plasmas.

Matter anything that has mass and takes up spaceThe word kinetic meansThree main parts of the theory:All matter is made of tiny particlesThese particles are in constant motion and the higher the temperature, the faster the particles moveAt the same temperature, heavier particles move slower. Kinetic TheoryStates of Matter:1. Solid2. Liquid3. Gas4. PlasmaParticles are tightly packedParticles vibrate in placeParticles can not flowConstant volumeHave very little energy1. Solid

Particles are loosely associated. Particles are able to slide past each otherParticles can flowConstant volumeHave a medium energy level

2. Liquid

LiquidsSpread out on their ownFluids- gases and liquids both flowViscosity- the resistance to flow; also called thickness.The better the molecules stick to each other, the more resistanceParticles are spread outParticles move all over the placeParticles can flowTake the volume of whatever container they are in. Have lots of energy3. Gas4. PlasmaLightning is a plasmaPlasma is a lot like a gas, but the particles are electrically chargedUsed in fluorescent light bulbs and neon lightsExtremely high energy levels

Plasma has no definite shape or volumeMoviePlasma StateKinetic Theory16.1All of the observed stars including the Sun consist of plasma. Plasma also is found in lightning bolts, neon and fluorescent tubes, and auroras.

Phase ChangesMolecules and atoms dont change during a phase change The composition doesnt changeThe mass doesnt changeThe volume does changeOnly the particle motion changesCondensationCondensation- Change from gas to liquidAs you cool a gas the molecules slow downAs gas molecules slow down they stick togetherExothermic

Vaporization Vaporization is a change of state from a liquid to a gasExamples are: Evaporation, Boiling

EndothermicSublimation

Sublimation is a change of state from a solid directly to a gasExamples are: dry ice and ice trays in a freezer.endothermicDeposition Deposition is a change of state from a gas directly to a solid.

Example is making dry ice.ExothermicFreezing

Freezing is a change of stateFrom a liquid to a solidexothermicExamples are: water to ice liquid lava to solid rock

Melting

Melting is the change of state from a solid to a liquidExamples are: Cheese on a hamburger Ice to waterendothermicMovie
