| TEMPERATURE… |
|||||||||
| is a
measure of the internal heat |
|||||||||
| energy of
a substance. The molecules |
|||||||||
| that make
up all matter are in constant |
|||||||||
| motion. By “internal heat energy”, we |
|||||||||
| really
mean this random molecular |
|||||||||
| motion. Molecular motion is therefore |
|||||||||
| the reason
any substance has a |
|||||||||
| temperature. The more the molecules |
|||||||||
| that make
up a substance move, the |
|||||||||
| the higher its
temperature. |
