Term
| Why does water have a great surface tension? |
|
Definition
| Because on the surface touching the air bonds become closer together bc water does not like to associate with air/break |

| What do h20 bonds do constantly? |
|
Definition
| they constantly break and reform |
|
|
Term
| What happens when water goes from 4 to 0C |
|
Definition
| The h2o bonds slowly form and reform and when it hits 0C the bonds lock together the farthest they can without breaking, the size increases but the density decreases. |
