alleryHENRY'S LAW states that at constant temperature:
AGas solubility is directly proportional to gas pressure
BGas pressure is inversely proportional to volume
CVapour pressure is proportional to mole fraction
DBoiling point is proportional to molality
Answer & Solution
Correct answer: A. Gas solubility is directly proportional to gas pressure
**HENRY'S LAW:** at constant T, gas solubility in a liquid ∝ pressure of the gas. Math: p = K_H × x.
**Applications:** soda fountains (CO2 dissolved under pressure), scuba diving (decompression sickness).
