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 increases with:

The solubility of $N_2$ in water at $300 \ K$ and $500 \ torr$ partial pressure is $0.01 \ g \ L^{-1}$. The solubility (in $g \ L^{-1}$) at $750 \ torr$ partial pressure is

Which of the following is a solution in which the physical states of solute and solvent are liquid and solid respectively?

Carbonated water is an example of a solution of

Air is a mixture of a number of gases. The major components are oxygen and nitrogen with approximate proportions of $20\%$ and $79\%$ by volume at $298\ K$. The water is in equilibrium with air at a pressure of $10\ atm$. At $298\ K$,if the Henry's law constants for oxygen and nitrogen are $3.30 \times 10^7\ mm$ and $6.51 \times 10^7\ mm$,respectively,the mole ratio of gases $(O_2 : N_2)$ dissolved in water is about
