Question

question 11
which of the early laws of gases describes the relation between volume and moles when temperature and pressure are constant?
daltons law
charless law
boyles law
avogadros law

Explanation:

• Dalton’s Law: Relates to partial pressures of gas mixtures, not volume - moles at constant T and P.
• Charles’s Law: Relates volume and temperature at constant pressure and moles.
• Boyle’s Law: Relates volume and pressure at constant temperature and moles.
• Avogadro’s Law: States that equal volumes of gases at the same temperature and pressure contain equal numbers of moles, so it describes the relation between volume and moles when temperature and pressure are constant.

Answer:

D. Avogadro’s Law
