Chapter U3, Problem 6RE

Interpretation Introduction

Interpretation : The correct graph corresponding to Boyle’s law has to be explained.

Concept Introduction : Boyle’s law states that when the temperature and quantity of gas are constant then pressure and volume have inverse relation with each other.

$PV=\text{constant}$

Here, $P$ is the pressure of gas and $V$ is the volume of gas.

Answer to Problem 6RE

Correct answer: The correct option is B.

Explanation of Solution

Reason for correct option: As seen in option B that pressure and volume are varying inversely with respect to each other. It is seen that as the volume is increasing the pressure on the other hand is decreasing. Thus, graph in option B satisfies the Boyle’s law.

Conclusion

Reasons for incorrect options: In option A, temperature is changing but at the conditions of Boyle’s law, the temperature is constant. Hence, option (A) is incorrect. In option (C), the direct relation between pressure and volume has been shown but they have inverse relation with each other according to Boyle’s law. Hence, option (C) is also incorrect.
