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 •

What is the latent heat of fusion

It is the amount of heat that is required to melt something, and the amount of heat that it gives off when it freezes. (They are the same amount.)
