Question

Account for the fact that aerated water bottle kept under water during summer

Answer 1

the aerated water bottle means the excess amount of oxygen and minerals are present in the water which dissolve under certain pressure and if this pressure suddenly decrease due to change in atmospheric pressure the bottle will certainly burst with decrease the amount of dissolved oxygen in water this tends to change the aerated water into normal water

Answer 2

$\huge{\underline{\underline {\mathtt{\purple{Hola\:}\pink{Mate}}}}}$

In aerated water bottles, Co, gas is passed through the aqueous solution under pressure since solubility of the gas in water is not very high. In summer, the solubility of the gas in water is likely to decrease since rise in temperature decreases solubility. Pressure becomes too high for the glass bottle to with stand and so explodes. To avoid this, bottles are kept under water.
