1. Heat 1. What are the definitions and the symbols for:
Heat – transfer of energy between two different temperatures (q)
Molar heat capacity - heat needed to increase the temperature of 1 mol of a substance by 1K (C)
Specific heat - heat needed to increase the temperature of 1 gram of a substance by 1K (cp)
Enthalpy – total energy of the system (H)
Entropy – measure of randomness (S)
Gibbs Energy – energy in a system available for work (G)

2. Heat 2. What are the equations needed to calculate: Heat – q=nCT
Enthalpy - Hreaction = Hproducts - Hreactants
Entropy - Sreaction = Sproducts - Sreactants
Gibbs Energy - Greaction = Gproducts - Greactants and G = H - TS
3. A property of a substance or system that is determined by the number of particles present in the system but independent of the particles themselves. (In other words, it doesn’t matter what it is but how much there is.) It lowers freezing point and raises boiling point.
