Water will form hydrogen bonds with other substances such as
glass, soil and plant tissues. The term for this type of attraction is known as
Adhesion
A combination of this and Cohesion can cause water to ‘defy
gravity’ by moving UP narrow tubes (such as the roots of trees) in a process
known as Capillary Action
**
Water is able to resist drastic changes in temperature because it
has a high Specific Heat (heat capacity)
Why is this important to us? (As humans)
We are made up of approximately 75% water as is the EARTH..... We rely on waters ability to store large amounts of heat in order for our planet to remain a livable temperature!!
Speaking of heat capacity..... Today was another brutal hot day, so you guys got to take it RELATIVELY easy. We just discussed specific heat again, moved into the importance of water being LESS dense as a solid than a liquid, and finally about how water is a great solvent. Here were the notes from Wednesday.
