Avogadro's Law

Who formulated Avogadro's law?

• Isaac Newton

• Amadeo Avogadro

• Albert Einstein

• Marie Curie

What is the relationship between volume and amount of gas according to Avogadro's law?

• Volume is proportional to pressure

• Volume is not related to amount

• Volume is directly proportional to amount

• Volume is inversely proportional to amount

What is the condition required for Avogadro's law to hold true?

• Low volume and high amount

• Variable temperature and pressure

• Constant temperature and pressure

• High volume and low amount
