17.

Explain the significance of Avogadro's law in understanding the behavior of gases.

Avogadro's law states that the temperature of a gas is directly proportional to its volume.

Avogadro's law explains the relationship between the mass of a gas and its volume.

Avogadro's law is used to calculate the pressure of a gas.

Avogadro's law helps us understand the relationship between the volume of a gas and the number of particles it contains.

18.

What are the assumptions made in Avogadro's law?

Equal volumes of gases contain different number of molecules at constant temperature and pressure.

Equal volumes of gases contain an equal number of atoms at constant temperature and pressure.

Equal volumes of gases contain an equal number of molecules at varying temperature and pressure.

Equal volumes of gases contain an equal number of molecules at constant temperature and pressure.

19.

State the mathematical expression of Avogadro's law.
