1. Starter question
Draw a diagram to illustrate what a coolling curve looks like
Draw a diagram to illustrate what a phase diagram looks like
Explain why the critical point is special

2. Solubility Diagrams
This is a solubility diagram. It shows how much of a substance can be dissolved at a certain temperature

3. The Solution Process
A solution is an example of an homogeneous mixture
When the solute particles separate from each other energy is either lost of gained
It is formed when a solute, is dissolved in a solvent
If the solvent is water we can refer to the solution as being an aqueous solution
If energy is lost we refer to the process as being exothermic
When a solution forms solute particles must separate from each other and mix with the solvent particles
If energy is gained we refer to the process as being endothermic

5. Solute
A substance dissolved in solution
Solvent
The substance that dissolves a solute to form a solution
Solution
A mixture of a solute and a solvent
Concentrated
Solution
A solution which has a large amount of solute dissolved
Dilute Solution
A solution which has a small amount of solute dissolved
Saturate Solution
A solution that contains the maximum amount od dissolved solute for a given amount of solvent at a specific temperature and pressure

6. Supersaturated
A solution that contains more dissolved solute than a saturated solution at the same temperature
Solvation
A process of surrounding solute particles with solvent particles to form a solution, occurs only where and when the solute and solvent particles come into contact with each other.
