|---|---|---|---|---|---|
| Is water the ????????? abundant compound in most living things | most! 80% of humans is water
🗑
|
||||
| Is water nuetral? | No it has a slight negative charge on one side and a slight posotive charge on the other!! (This property is called being polar)
🗑
|
||||
| the bonds between water molecules are caled:??? | Hydrogen bonds. They are weak temporary bonds.
🗑
|
||||
| cohesion | the attraction of water to itself. causes water to form a bead when dropped on a flat surface
🗑
|
||||
| adhesion | the attraction of water to other substances. caused because water is polor. sticks to the sides of thin tubes
🗑
|
||||
| capillary action | in a very thin tube water can rise due to adhesion and cohesion. This helps pulls water up the stem of a plants
🗑
|
||||
| surface tension | because of cohesion, things like a paper clip can float on water.
🗑
|
||||
| resistance to temperature change | heat must break hydrogen bonds before water heats up. Thats why the ocean is so cold in the summer and hotter than other liquids in the winter
🗑
|
||||
| What happens when water freezes? | the molecules will spread apart and have more air spaces this causes ice to float in water because it is less dense. Also if u fill a water bottle all the way and freeze it, it will break the cap because it expands
🗑
|
||||
| is water a good solvant | yes because the adhesion of water molecules is strong enough to break the hygrogen bonds water is polar and atracts more ions
🗑
