|---|---|---|---|---|---|
| Four Emergent Properties of Water- | cohesion/adhesion, moderation of temperature, evaporative cooling, excellent solvent
🗑
|
||||
| Cohesion/Adhesion- | water molecules stick together, which “holds water together” and gives water surface tension
🗑
|
||||
| Moderation of Temperature- | water resists change in temperature
🗑
|
||||
| Specific heat- | the amount of heat energy (gained or lost) required to change 1 g of a substance by 1 degree Celsius
🗑
|
||||
| Q. Why does water have a high specific heat- | A. it is a polar molecule and it forms hydrogen bonds
🗑
|
||||
| Evaporative Cooling- | reduction in the temperature of water resulting from evaporation of liquid
🗑
|
||||
| Solvent- | many substances have an affinity for water, they can partially or fully dissolve in it
🗑
|
||||
| Water dissociates- | water falls apart at low rates
🗑
|
||||
| Acid- | substances that increase the proton concentration
🗑
|
||||
| Base- | substances that decrease the proton concentration
🗑
|
||||
| Hydrophobic- | repels water
🗑
|
||||
| Hydrophilic- | has an affinity for water
🗑
|
||||
| 7 on pH scale- | neutral
🗑
|
||||
| Less than 7 on pH scale- | acid
🗑
|
||||
| Greater than 7 on pH scale- | base
🗑
|
||||
| Buffers- | minimize change in pH, proton concentration, and electron concentration
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
