5.) Use the kinetic theory to explain states of matter, phase changes, solubility, and chemical reactions.

Example: water at 25 degrees Celsius remains in the liquid state because of the strong attraction between water molecules while kinetic energy allows the sliding of molecules past one another

8.) Distinguish among endothermic and exothermic physical and chemical changes.

Examples:

- endothermic physical—phase change from ice to water,

- endothermic chemical—reaction between citric acid solution and baking soda,

- exothermic physical—phase change from water vapor to water,

- exothermic chemical—formation of water from combustion of hydrogen and oxygen

•  Calculating temperature change by using specific heat
•  Using Le Châtelier's principle to explain changes in physical and chemical equilibrium
