Document Summary
Cohesive: water molecules tend to stick to each other because they hydrogen bond to one another. There is so much strength in the hydrogen bonds that you can float things on top of it. Adhesive: water molecules tend to stick to other things because they hold hydrogen bonds to anything that is polar. It takes a lot of energy to make water change temperature. Because all of the water molecules are so tightly bonded it takes a lot of energy to make them all move faster or slower. The amount of energy it takes water to change state. It takes a lot of energy to make it change state because it takes a lot energy to break the hydrogen bonds. Less dense as a solid than a liquid. Ice floats because water as a solid is less dense than water as a liquid. To freeze someone without destroying the tissue, they remove all the water and replace it with anti-freeze.
