Why are gases more soluble in cold solvents?

Answer 1

yes,

the cooler the temperature the more gas is held, thingk of a soda bottle put it in the fridge and when you open it it will barely bubble, if it's room temp it foams a great deal...

that isn't my reason thats and example lol

the reason is the molecules are moving less so the aren't ousting the gas out.

Answer 2

Increasing temperature increases the kinetic energy of the molecules held within the solvent. If gases have a high enough kinetic energy, they can escape the solvent (which solids and liquids can't do, by the way, since they can't bubble up and out).

Answer 3

Keep in mind that gases have highly energetic molecules that want to stay apart from other molecules. As they are cooled, the energy decreases. Now the intermolecular forces between molecules might be strong enough to attract them to dissolve.

So the colder it gets, the more gas is dissolved.

Think of CO2 gas dissovled in a soda. Warm soda will go flat faster.
