Boyles law is a special case of the ideal gas law in which P1V1 = P2V2, stating that the volume of a gas is inversely proportional to pressure at a constant temperature. Which of these gases correctly demonstrates Boyles Law?

Correct Answer: A. A.
The correct answer is A. Looking at the graph for A, we see the pressure at point 1 is 10 kPa, and at point 2 is 25 kPa. The volume at point 1 is 50L. 50 x 10 = 500, and following Boyles Law, the volume at point 2 must be 500/25, or 20l. The other graphs do not show this correctly.
