Adhesion is when molecules stick to different things
What is adhesion?

Divide the mass of the object by its volume.
What is the way that you find density?
300
Capillary action is when the plant sucks water up the stem because of cohesion.
What is capillary action?
300
Yes, we do live in a watershed
Do we live in a watershed?

Surface tension is when water molecules hold on to each other and make a dome
What is surface tension?

All the water in the Colorado River eventually flows to the Gulf of California
Where does all of the water in the Colorado River flow eventually?
500
The properties of water can be a gas, liquid, or solid
What can the properties of water be?
500
Yes, you can break down a water molecule into atoms because hydrogen jumps when it gets struck by electricity.
