The variation of solubility for a gas with temperature can be determined by examining the graphic on the left.
As the temperature increases, the solubility of a gas decrease as shown by the downward trend in the graph .
More gas is present in a solution with a lower temperature compared to a solution with a higher temperature.
The reason for this gas solubility relationship with temperature is very similar to the reason that vapor pressure increases with temperature. Increased temperature causes an increase in kinetic energy. The higher kinetic energy causes more motion in molecules which break intermolecular bonds and escape from solution.
This gas solubility relationship can be remembered if you think about what happens to a "soda pop" as it stands around for awhile at room temperature. The taste is very "flat" since more of the "tangy" carbon dioxide bubbles have escaped. Boiled water also tastes "flat" because all of the oxygen gas has been removed by heating.

Entropy is what causes most of these solubility effects.
Entropy is a measure of disorder and it is favourable for this to increase. Also entropy becomes more of a factor the higher the temperature.
Gases have less entropy when dissolved
solids have more entropy when dissolved
So as T increases gases become less soluble and solids become more soluble.

What? It goes nowhere. Gases don't become more "soluble." Only liquid are soluble. As the temperature goes up, gases don't get more soluble or becomes less soluble.

Liquids become more soluble as the temperature is reduced. For instance when they are carbonating coca cola(adding CO2) the liquid's temperature is reduced to about 2 degrees as the gas is added.
The logic of this is that hot gas has faster molecules which tend to escape!

Solubility is higher at lower temperature. That is why carbolic drinks are advised to take after being chilled.

What you may desire to do is think of regarding the molecules and picture them shifting of their diverse states. In gases they circulate the quickest. even with the shown fact that that's chaotic. In a heated liquid there is multiple bumping and the molecules are close-greater possibilities to react. have you ever tried to combine table sugar into iced tea? It does not dissolve such as you have chose suitable? yet, in case you have warm tea, what happens?

as temperature increase solubility decreases.
Eg cold coke is more fizzy(co2 gas)
