There are four (4) basic principles that can be used to describes all chemical concepts. To explain a concept, one can utilize one or more of these principle.<br> <br> <u><b>Kinetic Molecular Theory (KMT)</u></b><br> Definition: All substance are made up of [[Particles]] (basic units) that are in constant motion (therefore has energy) and sometimes they interact/collide.<br> *There are two different ways that particles can interact/collide: **1) The components that make up the [[Particles]] can regroup to create new grouping (I call new [[Particles]]). We call this a Chemical Reaction (chemical change). Chemical reaction are based on Collision Theory at your level of understanding. The forces that are overcome to create the regrouping are called <b>Intramolecular Force</b>. **2) The components that make up the [[Particles]] <b>DO NOT REGROUP</b> so that [[Particles]] do not change but they just influence each other. We call this a Physical process. The influnece is called <nowiki>Intermolecular Force</nowiki> (IMF) *College Board AP chemistry does not use the name KMT but inside uses the phrase "particle view of matter". This means the same thing as KMT.<br> <br> <u><b>Conservation of Mass</u></b><br> Definition: Mass can not be gained nor lost in a physical process or chemical reaction. A more simple def is Mass is conserved.<br> *In general chemistry (excluding nuclear chemistry), we do not use Einstein equation, E=mc<sup>2</sup> which basically means that Energy (E) can be changed directly into matter (m). Not in our chemistry. <br> <u><b>Conservation of Energy</u></b><br> Definition: See above Conservation of Matter definition and replace mass with energy (including Einstein work)<br> <br> <u><b>Coulombic Force (those are my words, real name is Coulomb Law)</u></b><br> Definition: Same charge particles repel, different charge particles attract.<br> *If you are having a hard time understanding it, it is like when magnets interact *Feynman said that if all human knowledge was eliminated and you need one concept to figure out all other concepts, it would be Coulomb Law. <br>
