Chapter 13, Problem 71A

Interpretation Introduction

Interpretation:

The three major changes which take place by increasing the volume in the bases of observation in figure need to be explained.

Concept introduction:

various factors that are changing during the expansion of the gas such as temperature, volume pressure, and the number of moles.

Answer to Problem 71A

In a given graph, the volume of the gas becomes double or increased. So, following changes occurs which are given as

1. When volume is increased then pressure is decreased.
2. Temperature also increases with an increase in volume.
3. The number of moles increases with an increase in volume.

Explanation of Solution

1. According to Boyle’s law, the pressure is inversely proportional to the volume of the gas. So, the pressure is decreased with an increase in volume.
2. According to Charles’s law, the temperature is directly proportional to the volume of the gas. So, the temperature increases with increasing volume.
3. According to Avogadro law, the number of moles is directly proportional to the volume of the gas. So, the number of moles increases with an increase in volume.

Conclusion

As volume changes, then the pressure, temperature, and number of moles are also changing.
