Question

ventilation is governed by boyles law, which states that at a constant temperature,

the pressure of a gas is inversely proportional to its volume

the solubility of a gas is inversely proportional to its volume

the solubility of a gas is directly proportional to its volume

the pressure of a gas is directly proportional to its volume.

Explanation:

Boyle's Law states that for a given mass of an ideal gas at constant temperature, the pressure \(P\) and volume \(V\) are related by the equation \(PV = k\) (where \(k\) is a constant). This means that \(P=\frac{k}{V}\), so pressure is inversely proportional to volume. Solubility of a gas is related to Henry's Law (not Boyle's Law). And the relationship \(P\propto\frac{1}{V}\) (inverse - proportion) not \(P\propto V\) (direct - proportion).

Answer:

The pressure of a gas is inversely proportional to its volume.
