State Henry's law and give two of its applications.
Original Khojo Papers practice question — not from a past board paper.
Answer
Henry's law states that at constant temperature the mass of a gas dissolved in a given volume of liquid is directly proportional to the pressure of the gas above it. It explains why a soft drink fizzes when opened, and why a diver ascending too fast suffers from the bends as dissolved nitrogen comes out of the blood.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The solubility of a gas falls as the temperature rises, which is why warm water holds less oxygen.
