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 a flame test

Answer By exposing materials to a hot flame (from a Bunsen burner typically), the color of the flame can be used to identify the material. Certain elements give off a characteristic color when heated to high temperature. See the Related Links for "Wikipedia: flame test" to the bottom for the answer.
