ADalton's law
BHenry's law
CBoyle's law
DCharles' law
Answer & Solution
Correct answer: B. Henry's law
1. Blood is a liquid, so gases entering it obey the law that governs gases meeting liquids.
2. Henry's law states that the concentration of a gas in a liquid is directly proportional to its solubility and its partial pressure.
3. The greater the partial pressure, the more gas molecules dissolve.
4. Dalton's law deals with pressures within a gas mixture rather than with dissolving, so it is the wrong law here.
