To tackle this question, I’ll examine each listed gas law and match it to its defining relationship.
Option 1: Dalton's Law. This law states that in a mixture of non-reacting gases, the total pressure equals the sum of the partial pressures of the individual gases. It describes partial pressures in a mixture, not the direct relationship between volume and pressure for a single gas, so it does not answer the question.
Option 2: Henry's Law. Henry's Law relates the solubility of a gas in a liquid to the pressure of that gas above the liquid, linking gas solubility and pressure in solutions. It is not about volume-pressure behavior in gases, so it is not the correct description of the volume-pressure relationship for gases.
Option 3: Boyle's Law. This law precisely states that for a fixed amount of gas at a constant temperature, the pressure of the gas is inversely proportional to its volume (P ∝ 1/V), or equivalently P·V is constant. This is the classic volume–pressure relationship in gases and directly answers the question.
Option 4: Graham's Law. Graham's Law deals with the effusion or diffusion rates of gases and relates those rates to the molar masses of the gases. It does not describe how pressure and volume relate to one another, so it’s not correct here.
Option 5: Charles's Law. Charles's Law describes how a gas's volume changes with temperature at constant pressure (V ∝ T). It concerns temperature effects on volume, not the pressure–volume relationship at constant temperature, so it isn’t the law in question.
In summary, only Boyle's Law correctly describes the inverse relationship between pressure and volume for a gas at constant temperature and amount, while the other laws address different gas properties or conditions.
