 concentration | determined by the amount of solute dissolved in a solvent to make a solution |
| dilute | make less concentrated |
| volume | the amount of space an object takes up or occupies |
| the one with the greatest mass | when equal volumes of two solutions are compared on a balance, which one will be more concentrated |
| darkest, strongest taste, strongest smell, greatest mass | ways you can tell which solution is more concentrated |
| density | the amount of matter (mass) in a particular space (volume) |
| less than water | the density of an object that floasts on water, has a density that is |
| concentration rainbows | settle in layers with the most dense on the bottom and the least dense on top |
| Gatorade | is a solution because its ingredients are dissolved in water |
| solvent in Gatorade | water |
| most concentrated solute in Gatorade | sucrose syrup |
| least concentrated solute in Gatorade | brominated vegetable oil |
| nitrogen | the gas in air that is the solvent |
| oxygen, carbon dioxide | the solutes in air |
| global warming | is caused by an increase in carbon dioxide |
| troposphere | layer of the atmosphere closest to the Earth's surface, temperature and pressur drop as you go higher up |
| stratosphere | the layer directly above the troposphere, lower part has a nearly constant temperature with height |
| ozone layer | a thin layer above the stratosphere that absorbs most of the harmful ultraviolet radiation from the sun |
| mesosphere | directly above the ozone layer of the stratosphere, can slow down meteors |
| thermosphere | directly above the mesosphere, very hot temperatures |
| space | directly above the thermosphere |
| troposphere, stratosphere, ozone layer, mesosophere, thermosphere, space | the layers of the atmosphere in order from closest to farthest from the Earth |
