<u>What I have learned from 2015 Thermo section</u><br> *Need Webpage and video explaining the components of the Non-phase change heat equation <u>1st Lecture</u><br> * 3 Laws of Thermodynamics (Thermo) **1st Law of Thermo, Conservation of Energy ***Many ways of talking Energy, Two types, Kinetic energy (KE) and Potential energy (PE) <br> **2nd Law Thermo (not true definition but ours), Explains how energy moves. ***Energy flows from a higher temperature body to a lower temperature body until the temperatures are the same. ***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> ---------------------<br> <u>2nd Lecture</u><br> <b>1st Law of Thermo</b><br> *Equation of KE and types of KE **Temperature - Average kinetic energy (KE) of all the substance in a particle. Definition means that not all particles in a substance has the same KE. So have more KE than others. *Types of PE <br> <b>2nd Law of Thermo</b><br> *Ethalphy (H) - including energy of movement of particles from temperature, phase substance in, and energy keeping material that compose of the particle together (i.e. bond energy) *Energy and chemical reactions **Endothermic reaction - **Exothermic reaction - **Activitation energy *Spontaneous reaction - reaction that procedures without outside influence/energy added. **So no endothermic reaction can be spontaneous !!!! No, not correct. There is another energy component, Entropy. *Entropy and why you need a perfect crystal to be at absolute zero
