| A | B |
|---|
| Water Density of H2O | only substance less dense in solid form |
| Universal solvent | Everything can be solute (dissolved) |
| High Surface Tension | Great cohesion (bonding) with other substances |
| water is bent | natural dip in center, results in polar molecule |
| Meniscus | Natural dip in surface of water |
| Polar Molecule | +/- ends, strong attraction between opposites |
| why H2O is bent | sticks to surface that surrounds |
| How bent structure causes molarity | Strong attraction between opposite +/- ends |
| ice (solid) | 105 degree angle |
| liquid melted from heat | 109 degree angle |
| liquid most dense state | 4 degrees C |
| 75% | % of earth covered in H2O |
| 3% | % of fresh water |
| >than 1% | % available for human consumption |
| Why temperature does not increase or decrease | high specific heat (amount of heat for temperature change) |
| Why fresh water not available | pollution and polar ice caps |
| why snow and rain pure | filtered through water cycle |
