Which of the following contributes to the bubbling from a cold can of soda when left standing at room temperature. Choose all that apply.

1) the initial rush of CO2 out of the can drags other CO2 molecules out of the solution.
2) the decrease in CO2 partial pressure lowers the solubility of CO2 in the soda
3) the can gets warm
4) The CO2 molecules can only escape slowly, having trouble finding their way through the water molecules to the surface.

I think the answer is 1 and 3 but I am not sure.
