5005 Praxis Practice Test Practice Question
Which of the following graphs best illustrates Boyle's law, which indicates that the volume occupied by a fixed number of gas molecules is inversely proportional to the pressure, at a constant temperature?
Correct Answer: C
Rationale: Graph C accurately represents Boyle's law, demonstrating the inverse relationship between pressure and volume. As pressure increases, the volume decreases, which is depicted by a downward-sloping curve. This aligns with the principle that at a constant temperature, the product of pressure and volume remains constant.
Graph A likely shows a direct relationship, which contradicts the law. Graph B may represent a constant volume scenario, failing to illustrate the inverse nature. Graph D may depict a linear relationship, misrepresenting the non-linear correlation outlined in Boyle's law. Therefore, only Graph C correctly visualizes the relationship described.
