The solubility of a gas in a liquid increases with:

The correct solubility order of $AgF$, $AgCl$, $AgBr$, and $AgI$ in water is:

As temperature increases,the value of $K_H$ increases,thus the value of solubility of a gaseous solute will $ . . . . . . $.

The values of the Henry's law constant of $Ar$,$CO_{2}$,$CH_{4}$ and $O_{2}$ in water at $25^{\circ} C$ are $40.30$,$1.67$,$0.41$ and $34.86 \ kbar$,respectively. The order of their solubility in water at the same temperature and pressure is

When a bottle of soft drink is opened, which of the following phenomena occur?
$(A)$ Solubility of dissolved gas decreases.
$(B)$ The bottle releases internal pressure.
$(C)$ Effervescence is observed from the bottle.
$(D)$ Increase in external pressure.
Identify the correct choice.

The solubility of a gas in a liquid is directly proportional to the pressure of the gas over the solution. Identify the law for this statement.
