Solubility and Pressure
• In solids and liquids: Pressure has no effect on solubility.
• In gases: When the pressure increases, the solubility increases.
Gases are most soluble under
A closed can of soda has more pressure than an open can, so the gas is more soluble in the liquid, and the fizz stays in. When you open the can,
the pressure decreases, so the
solubility decreases, and the fizz (gas) escapes.

pressure.
(low temperature) with bottle cap on (high pressure). Ahh...!
