Why does an open can of soda stay carbonated for longer in the fridge, than it does at room temperature?

Answer 1

For most solutions, solubility increases with temperature. For CO2 in water however, solubility increases as temperature decreases (to a point pretty close to freezing)

This increased solubility means that the CO2 doesn’t try to escape as much in the fridge as it does in a warmer place
