• Water is known as the universal solvent because it can dissolve a large variety of chemical substances
• Specific Heat- The amount of heat energy required to raise the temperature of one gram of the substance by one degree Celsius
• The molecules in solid water are farther apart than they are in liquid water
• Phase Change - Transformations of matter from one physicalstate to another
• Heating Curve - A graph which shows the change in temperature of asubstance as it is being heated
• Phase Diagram - A graph giving the relationship among solid,liquid, and gaseous states of a given substance as a functionof the temperature and pressure
• Triple Point - the condition where the three phases of water is in equilibrium
• Critical Point - the condition when a liquid instantaneously turn into a vapor upon heating
