A soft drink (soda) can hold far more dissolved carbon dioxide under pressure than when opened to the atmosphere. You can hear the pressure released when you pop open a can. Cold soda can hold more dissolved gas than hot soda. Opening up a can of soda and heating it should drive out the excess carbon dioxide at the near-maximum rate. Shaking the can to created thousands of gas bubbles or nucleation points increases the amount of free surface in the can allowing gas to come out of solution even faster.

In soft drinks there is an equilibrium reaction going on.
The reaction is H2CO3 (aq) <-> H2O (l) + CO2 (g).
This is a endothermic reaction, i.e. energy is needed for the forward reaction. So the reaction here is likened to
H2CO3 (aq) + heat <-> H2O (l) + CO2 (g).
Adding heat shifts the equilibrium to the right by Le Chatelier's Principle and more CO2 is produced. (But the drink definitely becomes less fizzy after that)

I work in a soda bottling plant.I cant give a scientific answer,but I do know that a soft drink is bottled or canned when it is extremely cold.The bottles and cans are mushy.Most likly because cold is more condensed.Then they go thru a tunnel while being sprayed with hot water to give the product its hard rigid container.

it doesnt evolve when it is heated. it just displaces the carbon dioxide and releases it.
