Avogadro's Law states that equal volumes of all gases, at the same temperature and pressure, contain the same number of molecules. In simpler terms, if you increase the number of moles of a gas in a container while keeping the temperature and pressure constant, the volume of the gas will increase proportionally. This is often expressed as $V_1/n_1 = V_2/n_2$, where V is volume and n is the number of moles. This law is super helpful for relating volume and moles when dealing with gases!
Match each term with its definition:
| Term | Definition |
|---|---|
| 1. Mole | A. The amount of space a substance occupies. |
| 2. Volume | B. A measure of the average kinetic energy of molecules. |
| 3. Temperature | C. A substance in the gaseous state. |
| 4. Gas | D. A unit of amount, defined as $6.022 \times 10^{23}$ entities. |
| 5. Constant | E. A value that does not change. |
Avogadro's Law describes the relationship between the ______ and the number of ______ of a gas, when ______ and ______ are kept constant. As the number of moles increases, the ______ also increases.
Imagine you have two balloons of the same volume. One is filled with helium and the other with carbon dioxide, both at the same temperature and pressure. According to Avogadro's Law, what can you conclude about the number of gas molecules in each balloon?
