- Kinetic Theory of Mater - States of matter - Phase changes - Classes of Matter - Properties of Matter - Conservation of Mass

 a theory that matter is composed of small particles, all in random motion.

 Solid  Liquid  Gas  Plasma

 Constant volume (fixed and wont change)  Constant shape  VERY slow movement of particles or only vibrate  Low energy (very little energy)  4 types  Ionic  Covalent  Molecular  Metallic

 Volume is constant (same)  Shape is NOT constant, it changes depending on the container  Particles move more quickly  Energy is higher than solid  Other  Viscosity --The resistance of a liquid to flow is called its viscosity  Surface Tension -- The result of attraction between molecules of a liquid which causes the surface of the liquid to act as a thin elastic film under tension. Surface tension causes water to form spherical drops.  Vapor Pressure -- The pressure that a solid or liquid exerts when it is in equilibrium with its vapor at a given temperature.  Boiling Point -- when vapor pressure = atmospheric pressure.

 Not fixed Volume  Not fixed Shape, will take the shape of the container  Movement of particles is faster than a liquid  Higher energy than liquid or solid  Other- all the gases more or less obey the gas laws. The gas laws deal with how gases behave with respect to pressure, volume, temperature, and amount.

 Not fixed volume  Not fixed shape  Fastest particle movement  Highest energy  Plasma is an ionized gas, or a gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species, ions and electrons, to coexist.  plasma is a cloud of protons, neutrons and electrons where all the electrons have come loose from their respective molecules and atoms, giving the plasma the ability to act as a whole rather than as a bunch of atoms.  Plasmas are the most common state of matter in the universe comprising more than 99% of our visible universe and most of that not visible.  On earth, plasma is naturally occurring in flames, lightning and the auroras. And can be seen in neon lights

Exothermic- reactions that release energy -Recombination -Deposition -Freezing Endothermic- reactions that must take in energy to occur -Ionization -Sublimation -Melting

Elements Same and Fixed Particles Cant be broken down (simplest of forms) Only one type of atom Same properties throughout EX- Carbon, Oxygen, Gold (any atom on the Periodic Table) Compounds Different but Fixed Particles Can be broken down into elements 2 or more elements in a fixed proportion EX- water (H2O) silicon dioxide (SiO2) Mixtures Different and NOT Fixed Can be broken down to compounds and elements and other mixtures Properties vary Uniformity is all different EX- Salsa or sand

-Physical Properties= properties that don’t change the make up of a substance -Chemical Properties= properties that change the make up of a substance
