Describe each of the three states of matter.
A gas has no definite shape and no definite volume. The molecules are very spread out. A liquid has a definite volume but no definite shape. The molecules are spread out, but not as much as those in a gas. A solid has a definite shape and a definite volume. The molecules are tightly packed together.

Explain all four changes in state of matter.
Melting is the change in state from solid to liquid. Freezing is the change in state from liquid to solid. Condensing is the change in state from gas to liquid. Evaporating is the change in state from liquid to gas.

Explain the difference between the reactants and the product. What were the reactants and what was the product in the investigation we did?
The reactants are the starting substances in a chemical reaction and the product is the new substance created after a chemical reaction. The baking soda and the vinegar were the reactants. The carbon dioxide was the product.
