Question

There are two open cans of soda on the table. One can was just taken from the refrigerator and the other was taken from the cupboard. Upon opening the cans, which one loses carbon dioxide more quickly and why?

Answer 1

The one from the cupboard because it is warmer (has more thermal energy) than the one from the refrigerator. When a liquid becomes warmer, the solubility of a gas becomes lower. Therefore, there is already more CO2 in its gaseous state when the soda is warm. Also why drinking coke cold tastes more bubbly cold than when warm.

Answer 2

The can of soda that was taken out of the cupboard loses carbon dioxide more quickly.

Step-by-step explanation:

Solubility of gases deceases with increase in temperature. As the temperature increases the kinetic energy of the gas particles increases, causing the gas molecules to overcome the intermolecular forces of attraction, allowing them to escape from the solution phase to the gas phase. Thus the can of soda that was taken out of the cupboard loses carbon dioxide faster than the soda can taken out of the refrigerator.
