The solubility of a gas in a liquid increases with:

Which of the following statement$(s)$ is/are correct regarding the solubility of solid $I_2$?

If $CO_2$ gas having a partial pressure of $1.67 \ bar$ is bubbled through $1 \ L$ water at $298 \ K$,the amount of $CO_2$ dissolved in water in $g \ L^{-1}$ is approximately. (Henry's law constant of $CO_2$ is $1.67 \ kbar$ at $298 \ K$)

Which of the following graphs correctly represents the plots of $K_{H}$ for gases in water versus temperature?

If $N_2$ gas is bubbled through water at $293 \ K$,how many millimoles of $N_2$ gas would dissolve in $1 \ L$ of water? Assume that $N_2$ exerts a partial pressure of $0.987 \ bar$. The Henry's law constant for $N_2$ at $293 \ K$ is $76.48 \ kbar$.

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.
