1. Examples-Colligative Properties

2. Example Rubbing alcohol is a solution of 50% C 2 H 5 OH and water. Would you expect rubbing alcohol to conduct electricity? Would you expect it to freeze at zero degrees Celsius?

3. Example Car engines are cooled by water. However, as water freezes it expands, how is it possible to have water cooler car engines in the winter when temperatures dip below the freezing point?

4. Example At high elevations water boils at lower temperatures. How could you correct for this?
