Chemistry of Life
| Question | Answer |
|---|---|
| The type of chemical bond that forms a water molecule (this is a strong bond) | Covalent Bond |
| The type of chemical bond that can form BETWEEN water molecules (these are weak, temporary bonds) | Hydrogen Bonds |
| Having an uneven distribution of electrons results in a ________ molecule | Polar |
| Property of water where water molecules stick together because they form hydrogen bonds with each other | Cohesion |
| Property of water where it sticks to hydrophilic surfaces because water forms hydrogen bonds with those surfaces | Adhesion |

| Having the ability to absorb a lot of heat energy before the temperature rises | High Specific Heat |
| Property of water that allows some mammals to cool down by sweating or panting | High Heat of Vaporization |
| Having the ability to absorb heat energy in the process of changing from a liquid to a gas | High Heat of Vaporization |
