Thermodynamics:
Study of heat changes.

Temperature (T):
Proportional to the average kinetic energy of the particles.  The higher the temperature the faster the molecules move.

 Zeroth Law of Thermodynamics:
Objects in thermal equilibrium are at the same temperature. Objects in contact will eventually come to thermal equilibrium.

 1st Law of Thermodynamics (Law of Conservation of Energy):
Energy cannot be created nor destroyed in a chemical or physical process.

 Calorimetry:
Energy lost/gained from the system is equal & opposite to that lost/gaines from the surroundings

 Entropy (S):
Disorder or random-ness

2nd Law of Thermodynamics:
The total entropy of the universe can never decrease. 

In this tutorial, the laws of thermodynamics are described.  The 0th law says that objects in thermal equilibrium have the same temperature and no heat is exchanged.  The 1st law says that energy isn’t created or destroyed, it changed from one form to another.  The 2nd law says that the disorder, or entropy, of the universe won’t decrease.  It will either increase or stay the same.
