| Surface Tension | the attraction of water molecules to each other creating a skin like bonding on the surface of water |
| density | the relative mass of a certain amount of a substance |
| thermocline | the boundry of warm surface water and the colder water underneath |
| evaporation | liquid turning into a vapor |
| condensation | a vapor turning into a liquid |
| water vapor | water in the form of a gas, you get this when water evaporates |
| warm water is more/less dense than cold water | less |
| salt water is more/less dense than fresh water | more |
| when a dish of salt water is set in the sun it will become more/less dense due to evaporation | more (fresh water evaporates out leaving the salt in less water than before) |
| cooling water will make it more/less dense | more (up until almost freezing) |
| wood is more/less dense than water | usually less dense (there are some woods that will actually sink in water) |
| the reason that the water bunched up on the penny | surface tension |
| the reason that water sticks to something | adhesion |
| the first weight you move on the balance is the largest/smallest | largest |
| you read the graduated cylinder at the top/bottom of the "bubble" | bottom |
| the "bubble" in the graduated cylinder is caused by _____. | adhesion (of water to the side of the cylinder) |
| 50 ml of water would have a mass of about ____ grams. | 50 |
| If you were to pour fresh water into a cup of salt water would the new mixture be more or less dense. | less |
