Term
| Which experiment demonstrated chemical energy? |
|
Definition
| The salt solution experiment demonstrated a chemical reaction. The energy that was transferred from the battery to the water created bubbles. These bubbles were were created when the water molecules were being separated into hydrogen molecules and oxygen molecules. Remember a water molecule is made of two hydrogen molecules and one oxygen molecule. |
