properties of water

Well as many of you know, water has very many properties.  For now i just like to focus on its physical properties.  Water has four of these, adhesion, cohesion, surface tension, and specific heat.  Cohesion is when all of the positively charged hydrogen molecules are bonded to the negatively charged oxygen molecules.  This allows the water to defy gravity in some situations.  An example of this is trees.  The water molecules travel all the way from the base to the leaves.   Another example was in our lab.  We tried to cut the water with the toothpick but the molecules stuck to each other instead of the toothpick or the wax paper.   Adhesion is when water(a liquid) is bonded to a solid.  This is also how a tree gets water to its leaves.  The water molecules stick to the tubules in a tree.  Another example of adhesion was in our last lab.  The water traveled down the string because the molecules stuck to it.  Surface tension is the amount of force it takes to break the bonds of water molecules.   Some objects have enough mass to break through the bonds but others can literally walk on top of water.  My example of surface tension is the childhood game of red rover.  The linked hands are the bonds of water molecules.  The other team sends a person or a water drop to try and break the bond.  If this person's mass is great they will break this bond.  If it is of lesser mass then they will not break the bond, instead they will become apart of it.  This also reminds me of the previous lab. The penny just kept collecting water drops.  At first the bonds were very strong, but after every drop they became weaker until finally all the bonds broke and the water overflowed onto the table.  This is also cohesion.  The last property i would like to talk about is Specific Heat.  Specific Heat is the amount of heat it takes to raise one gram of water one degree Celsius.  Water has a high specific heat because it is designed to easily bond together.  When water is heated most of the energy is used to break the bonds of the molecules first instead of being used to heat the molecules.  Water is able to withstand numerous heat changes.  This describes why earth's climates vary so much.  This is what i have learned from the lab and the properties of water videos.
