Why is a soda water bottle kept in a cold place?

Calculate the concentration of dissolved gas in water at $25^{\circ} C$ if the partial pressure of the gas at the same temperature is $0.15 \ atm$. $\left[K_H = 0.15 \ mol \ dm^{-3} \ atm^{-1}\right]$ (in $M$)

The statement "The mass of a gas dissolved in a given mass of a solvent at any temperature is proportional to the pressure of the gas above the solvent" is

Explain the equilibrium in soda water and explain it using Henry's law.

Calculate the solubility of a gas in water at $260 \ mm \ Hg$ and $25^{\circ} C$ if Henry's law constant of the gas is $0.159 \ mol \ dm^{-3} \ atm^{-1}$ at $25^{\circ} C$.

The solution of sugar in water contains
