(i) According to Henry’s law, 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.
(ii) On shaking the cold drink bottle the pressure of the gas inside the bottle increases. When the bottle is opened, the pressure tends to decrease to atmospheric pressure. As the pressure decreases, solubility decreases and hence, the dissolved gas along with the water escapes out.
(iii) Carbon dioxide .
(iv) No, it will decrease as solubility decreases with increase in temperature.
(v) Sonu and Manu, are naughty, intelligent and curious children.
