<br> Definition of Thermodynamic<br> <br> <br> <center><u>Three Laws of Thermodynamics (Thermo)</u></center><br> *1st Law of Thermo, Conservation of Energy **Many ways of talking Energy, Two types, Kinetic energy (KE) and Potential energy (PE) **For AP student, deltaE = w + q where deltaE = internal energy, w - work, and q = heat *2nd Law Thermo (not true definition but ours), Explains how energy moves. **Simple Explanation comes in 2 parts: <br> **1) Energy flows from a higher temperature body to a lower temperature body until the temperatures are the same.<br> **2) When energy moves (especially from one form of energy to another), you "lose a little" of it. **Need to define Temperature - average Kinetic energy (KE) of all the particles in a substance <br> *3rd Law of Thermo, Condition of No Energy ***Absolute zero is the condition of no energy that requires 0K (0 Kelvin temperature, no movement or KE of particles) and a perfect crystal. ***Can't reach absolute zero, so all substances or systems have energy. <br> Note: You can not measure or quantify how much energy a system or substance unless it is flowing.<br> <br> *For Chemical Reaction, there are 3 questions always asked:<br> *1) Does reaction occur? *2) How fast does reaction go (rate of making products) *3) How or by what mechanics do the reactants become product *<b>Thermodynamics only answers 1st Question, Does reaction occur or not.</b><br>
