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 solution
A liquid with something dissolved in it
How much energy is required to raise the temperature of 3 kg of iron from 20C to 25C
What is specific heat a measure of
The amount of energy it takes to change the temperature of a
substance by a certain amount.
How much energy it takes to heat a substance ~APEX
What happens to the entropy in the reaction I2s I2g
Entropy increases in the reaction.
What is the entropy of a solid based on
The arrangement of the atoms
Which equation shows how frequency is related to velocity and wavelength
What does thermal energy refer to
The kinetic energy within a system
What information does Gibbs free energy give about a reaction
It tells if the reaction will process spontaneously or not
