Types of Energy
Chemical Energy: Energy stored in the bonds between atoms in molecules. For
example, a leaf uses sunlight to bind carbon dioxide and water molecules into a sugar
molecule. It stores the solar energy in the chemical bonds of that sugar mole

A Gas Uniformly fills any container
Mixes completely with any other gas
Can easily be compressed
Exerts pressure on its surroundings
The properties of a gas depends upon four variables Pressure (P)
Is equal to force/unit area
THE DENSITY OF GASES
We already know the equation of ideal gas law (PV=nRT), but now we can rearrange the gas law to solve
for densities and molar masses! This is how we can derive a new equation so solve for density (g/L).

1. A 3.10 mL bubble of methane gas forms at the bottom of a bog where the temperature is 12oC and the
pressure is 8.5 atm. The bubble rises to the surface where
Boiling Points of Solutions - Acc Chem I
You may know that the boiling points and freezing points of a solution are different from the boiling and
freezing points of a pure solvent. Adding a solute to a solvent elevates the boiling point and lowers the

Interpreting Solubility Curves
Solubility is a measure of the amount of solute that will dissolve in a given amount of
solvent usually water. A solubility curve shows how much solute dissolves in a given
volume of solvent at a given temperature. How
