According to Henry's Law, what is the relationship between gas solubility and partial pressure?

Henry's Law states that the amount of gas that dissolves in a liquid is directly proportional to the partial pressure of that gas above the liquid. This means that as the partial pressure of the gas increases, more of that gas will dissolve into the liquid until a saturation point is reached. This relationship is crucial in many medical and physiological contexts, particularly in understanding how oxygen and carbon dioxide behave in the bloodstream under varying conditions of pressure, such as during hyperbaric treatments or in environments with fluctuating atmospheric pressures.

Therefore, the correct choice reflects the fundamental principle outlined in Henry's Law, highlighting that an increase in partial pressure leads to an increase in gas solubility in the solvent. This understanding is important for paramedics and healthcare professionals when assessing respiratory function or managing conditions related to gas exchange in the body.
