Question

How does Avogadro's law explain Gay-Lussac's law of gaseous volumes?

Answer 1

• According to Avogadro's law, equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.
• Since gases react in a simple ratio by the number of molecules, volumes of the gaseous reactants and products will also bear a simple whole-number ratio to each another. This is what Gay Lussac's law states.
