Question

Opening a cold can of soda pop from the refrigerator and pour it into a glass. It contains CO₂ gas molecules dissolved in water. If you leave the soda pop sitting on the counter at room temperature and come back in an hour and check it. Do you see bubbles in the glass? Does this mean that the solubility of CO₂ gas increased or decreased with increasing temperature?

Answer 1

Solubility of a gas in a liquid depends on many factors. Temperature is one of them ,that is solubility of a gas is inversely proportional to temperature.. On increasing temperature(when the soda pop is brought down from chilling temperature to room temperature) , the solubility of the gas decreases so the bubbles keep evolving initially as the temperature rises but after some time when all the gas has evolved then evolving of bubbles stop.

So initially bubbles do evolve but after 1hour bubbles evolve very less as by that time already the gas has evolved due to rise in temperature and reduction in solubility.
