Chapter 13.2, Problem 31SSC

Interpretation Introduction

Interpretation:

Avogadro’s principle holds good for gases having small particles.

Concept introduction:

The change in volume of the gas on changing the mass of the mass of the gas is studied by a law named as Avogadro’s Law.

According to this law,

$\begin{array}{l}V\propto n\\ \end{array}$

Where

$\mathrm{V}$ is volume of the gas

$\mathrm{n}$ is the number of moles of the gas

Answer to Problem 31SSC

Avogadro’s principle holds true for gases having small particles because small particles follow kinetic molecular theory and behave ideally.

Explanation of Solution

Small particles take less volume. Their distance from other particles is also large, due to which inter-particle attractions are very small. In nutshell, postulates of kinetic theory are followed by small particles. So gas behaves ideally and follow Avogadro’s law of ideal gases.

Conclusion

Gases having small particles follow Avogadro’s law.
