Question

Explain the following observation: Aerated water bottles are kept underwater during summer.

Answer 1

Hint: We know Gay Lussac’s Law; at constant volume the temperature and the pressure of the gas are proportionally related.
$\dfrac{P}{T} = K$
Where,
P is the pressure of the gas.
T is the temperature of the gas.
K is the constant.

Complete step by step answer:
We know that, Pressure is straightforwardly corresponding to temperature. As the temperature increments in summer, the pressure of the gas inside the container will increment. Moreover the dissolvability of the broken down gas diminishes with increment in temperature. To keep away from the jugs blasting open because of expansion in pressure, they are kept in water. Water retains heat all the more gradually because of its higher inert warmth of vaporizations.
Circulated air through water contains \[C{O_2}\] gas disintegrated in watery arrangement under tension and jugs are very much a stopper. As in summer the temperature increases and we realize that the solvency of the gases diminishes with the expansion of temperature and accordingly a greater amount of gas is required to be produced in the container consequently pressure applied by the gas in the jug will increment. On the off chance that the containers are not kept submerged, the gas created might be huge in amount and thus pressure applied by the gas might be exceptionally high and the jug may detonate. Thus, to diminish the temperature and subsequently to maintain a strategic distance from the blast of the containers.

Note: Gay-Lussac utilized the formula gained from \[\dfrac {\Delta V}{V} = \alpha \Delta T\] to characterize the pace of extension α for gases. For air he found a relative development $\dfrac{{\Delta V}}{V} = 37.50\% $\[\dfrac{\Delta V}{V} = 37.50\% \] and got an estimation of \[\alpha = 37.50% /100^\circ C = \dfrac{1}{266.66^\circ C\}] which demonstrated that the estimation of outright zero was around \[266.66^\circ C\] beneath \[0^\circ C\] .The estimation of the pace of extension α is roughly the equivalent for all gases and this is additionally once in a while alluded to as Gay-Lussac's Law.
