Explanation: A scientific question has some characteristics. It should not be vague it should have some real answers. It should be testable, means it can be tested by an experiment, it should be repeating means the results can be obtained anywhere by following the same methods, it should lead to a hypothesis that is falsifiable.

If 56.5 m3 of a gas are collected at a pressure of 455 mm Hg, what volume will the gas occupy if the pressure is changed to 632

ExtremeBDS [4]

Assuming ideal conditions, Boyle's law says that

P₁ V₁ = P₂ V₂

where P₁ and V₁ are the initial pressure and temperature, respectively, and P₂ and V₂ are the final pressure and temperature.

So you have

(455 mm Hg) (56.5 m³) = (632 mm Hg) V₂

==> V₂ = (455 mm Hg) (56.5 m³) / (632 mm Hg) ≈ 40.7 m³
