Question

Opening a soda bottle illustrates how a decrease in pressure will___the amount of gas that can be dissolved in water.

Answer 1

Answer: The correct answer is Option b.

Explanation:

This solubility of a gas with change in pressure is described by Henry's Law.

This law states that the mass of a gas dissolved in a given volume of the liquid at constant temperature is directly proportional to the pressure of the gas present in equilibrium with the liquid.

Mathematically,

$m\propto p$

or,

$m=Kp$

Where, m = mass of the gas dissolved in a unit volume of the solvent

K = Proportionality constant

p = Pressure of the gas in equilibrium with the solvent.

With increase in pressure, the mass of gas dissolved will also increase and vice-versa.

Hence, the correct answer is Option b.

Answer 2

C. Increase :)
I would choose C
