Praxis 5005 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: Boyle's Law states that pressure and volume are inversely related when temperature is constant. Graph C effectively illustrates this relationship, showing a downward curve where increasing pressure leads to a decrease in volume, confirming the inverse proportionality.
Option A likely depicts a direct relationship, which contradicts Boyle's Law. Option B may illustrate a constant volume scenario, failing to represent the pressure-volume relationship. Option D could show a linear relationship, which does not align with the expected curvature of the inverse relationship. Thus, only Graph C accurately reflects Boyle's Law.
