Chapter U3.58, Problem 2E

Interpretation Introduction

Interpretation: Comprehend the variation of trapped gas pressure with volume.

Concept Introduction: The volume is defined as the space taken up by an object. Thus, the volume is a measure of complete size of an object.

Explanation of Solution

The gas pressure is inversely proportional to the volume of gas. This is because as the gas pressure increases, the gas particles come close to each other. It decreases the intermolecular distance between particles and volume decreases.

Similarly, as the pressure decreases, the intermolecular distance between particles increases that increases the volume of gas.

Conclusion

  $\text{Pressure α }\frac{\text{1}}{\text{volume }}$
