| \( V_1 \) = First Volume of Gas | \( in^3 \) | \(mm^3 \) |
| \( n_1 \) = First Amount of Gas | \(mol\) | \(mol\) |
| \( V_2 \) = Second Volume of Gas | \( in^3 \) | \( mm^3 \) |
| \( n_2 \) = Second Amount of Gas | \(mol\) | \(mol\) |
Avogadro's law, also called Avogadro's gas law, one of the Gas Laws, when temperature and pressure are held constant, states that, at the same temperature and pressure, equal volumes of different gases contain the same number of molecules.
This law shows that the ratio of the volume of a gas to the number of moles of the gas is constant, as long as the temperature and pressure remain constant. This means that if the number of moles of a gas is doubled, the volume of the gas will also double, as long as the temperature and pressure remain constant. This law is an important concept in chemistry and physics, and is used to explain the behavior of gases and the properties of materials.
