| Where does evaportation happen? |
|
Definition
| at the surface of a liquid |
|
|
Term
| Explain how your seat evaportates. |
|
Definition
The sweat absorbs energy from your skin, and is able to break the attraction, and be set free. |
|
|
Term
When the sweat evaporates you feel...
and Why |
|
Definition
Cooler
because The energy is transferred to the sweat, leaving you with less energy (heat) |
|
|
Term
| What is the difference between evaprotation and boiling? |
|
Definition
Evaporation can happen below the boiling point and only at the surface. Boiling causes vaporization throughout the liquid and happens at the boiling point. |

| What is the difference between the gas in the helium thank, and in the balloons? |
|
Definition
| The helium in the tank has a great density because more molecules are packed into a smaller area, in the balloon the molecules are farther apart. |

|
Definition
move freely
collide randomly
little attraction to each other

|
Definition
gas can be compressed because it has more open space.
- liquids can be compress but not as much due to a lack of space
-solids can't be compressed because the molecules are already compressed |
