Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Boyle's Law states that for a fixed mass of gas at constant temperature, $PV = \text{constant}$.
Step 2: Meaning
No matter how much you change $P$ or $V$, their product remains the same as long as temperature doesn't change.
Step 3: Analysis
In a graph of $PV$ vs $P$, since $PV$ is a constant value, the y-coordinate remains fixed while the x-coordinate ($P$) increases.
Step 4: Conclusion
This results in a horizontal straight line parallel to the pressure (x) axis.
Final Answer: (A)
