The boiling point of a substance is a characteristic property which does not depend on quantity. It is one method used to help identify a particular liquid. In this experiment, the student will be given two liquids: isopropyl alcohol and an unknown. The student will determine the temperature at which they boil and identify the unknown according to its boiling point. You will repeat the process for each liquid three times in order to get the most accurate results.
