What does Avogadro's Law relate to in terms of gases?

• A. Pressure and temperature
• B. Volume and amount of gas
• C. Temperature and density
• D. Mass and pressure

Answer: (B)

Avogadro's Law states that under the same conditions of temperature and pressure, equal volumes of all gases contain an equal number of molecules, regardless of the type of gas. This law directly relates to the volume of gas and the amount of substance (in moles) present. It implies that if you double the number of moles of a gas at constant temperature and pressure, the volume will also double. This relationship emphasizes that the volume occupied by a gas is directly proportional to the number of moles of gas, hence establishing a clear connection between volume and the amount of gas. By keeping temperature and pressure constant, Avogadro's Law provides a fundamental understanding of how gas behavior scales with the number of particles, which is crucial in thermodynamics and other applications involving gaseous substances.
