Which properties of water are due to water being polar?
2 Answers. The polarity of water molecules means that molecules of water will stick to each other. This is called hydrogen bonding. Polarity makes water a good solvent, gives it the ability to stick to itself (cohesion), stick to other substances (adhesion), and have surface tension (due to hydrogen bonding).
What is the first property of water?
The first two properties that we will discuss in our AP® Biology Crash Course Review are related to each other: adhesion and cohesion. Adhesion is the property of water that refers to water molecules sticking to another surface. Cohesion is the property of water that refers to water molecules sticking to each other.
