What I have learned from 2015 Thermo section
Need Webpage and video explaining the components of the Non-phase change heat equation
1st Lecture
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)
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
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.
Note: You can not measure or quantify how much energy a system or substance unless it is flowing.
2nd Lecture 1st Law of Thermo
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
2nd Law of Thermo
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
