Properties of water
| Question | Answer |
|---|---|
| polar molecule | a molecule that has electrically charged areas. H20 consists of polar molcules so it is a polar substance. |
| capillary action | (water going up a straw; into bricks) the combined force of attraction among water molecules and with the molecules of surrounding materials (straw, brick) h20 seeps up |
| surface tension | the tightness across the surface of water that is caused by the polar molecules pulling on one another |
| solution | a mixture that forms when one substance dissolves in another |
| solvent | a substance (water) that dissolves another substance (kool aid). h2o is a solvent. |
| speicific heat | The amount of temp needed to increase the temp of another substance by 1degree celsius. |
| evaporation | (liquid to gas) h2o molecules at the surgace of a liquid absorb energy and change from a liquid to a gas |
| condensation | (gas to liquid) The change of state from a gas to a liquid |
