What is thermodynamics
the study of the movement of energy and heat.
or
Thermodynamics is the branch of physics concerned with the conversion of different energy forms.
•DeltaG (rxn) = DeltaG (pdts) - DeltaDG (rcts) •DeltaG°(rxn) = -R T ln K •
How is an endothermic reaction identified
It requires heat as a reactant.
Who created the model of the atom that has quantizied levels of energy
Which of the following describes the entropy change of a gas reaction

1kJ 1/Hfusion g/mol solid
What is a result of the specific heat differences between land and ocean
Breezes are created when there are specific heat differences between land and ocean.
How is the Hfusion used to calculate the energy released when a mass of liquid freezes
Grams Liquid x mol/g x Hfusion
How does the H reaction relate to the Hf of molecules involved in a reaction
Hreaction = Hf products - Hf reactants
