Why is it that the contents of a bottle of soda opened at room temperature tend to expand all over the persons hand’s holding the bottle, but the same bottle if opened when chilled just makes a slight hissing sound?
1. The carbon dioxide gas intentionally dissolved in the soda is more soluble at lower temperatures.
2. The bottle allows more gas to expand through the pores of the plastic at lower temperatures.
3. The bottle shrinks at low temperatures, creating less headspace for the gas above the soda, which means more gas dissolves in it, so less escapes when the bottle is opened.
4. The nitrogen gas intentionally dissolved in the soda is more soluble at lower temperatures.
