Which proportionality shows the result of combining Avogadro's law with Boyle's law? V is proportional to StartFraction 1 over nP EndFraction. V is proportional to StartFraction n over p EndFraction. V is proportion to StartFraction P over n EndFraction. V is proportional to n P.

V is proportional to StartFraction n over p EndFraction.

Explanation:

Let us remind ourselves of the statements of both Boyle's law and Avogadro's laws.

Boyle's law states that, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.

Avogadro's law states that at the same temperature and pressure, equal volumes of gases contain equal number of molecules.

Hence;

V α 1/P (Boyle's law)

V α n (Avogadro's law)

V α n/p (combination of Boyle's law and Avogadro's law)
