1.     Oxygen - atom in water that attracts electrons more strongly

2.     Polar - a molecule with an uneven distribution of charge

4.     Hydrogen bond - attraction of a hydrogen for a more negatively charged atom such as oxygen or nitrogen

5.     Cohesion - attraction between molecules of the same kind

6.     Adhesion - attraction between molecules of different kinds

7.     Capillarity or capillary action - tendency of water to rise in a narrow tube due to adhesion and cohesion

8.     Molecular Motion - Molecular motion is how the molecules move and the energy associated with the movement affects the physical properties of a chemical. Molecules can move in three ways, transitional, rotational, and vibrational.
