alleryStart learning →Henry's law states that the quantity of an ideal gas dissolving in a liquid is proportional to:
AThe colour of the gas
BThe age of the sample
CThe pressure of the gas
DThe mass of the liquid
Answer & Solution
Correct answer: C. The pressure of the gas
1. Gas solubility responds to one variable in particular.
2. Henry's law concerns the quantity of an ideal gas that dissolves in a definite volume of liquid.
3. That quantity is directly proportional to the pressure of the gas.
4. Opening a fizzy drink drops the pressure and the gas comes out of solution.
