Harrison Melendez · Answer 1

When water vapor condenses it adds heat to the wall of the bottle.

That same energy passes through the bottle and into the soda.

This is not the only heat transfer going on in the example. Warm air molecules also add heat to the bottle, and if it's sitting in the sunlight, the bottle receives radiant heat from the sun.

If you could measure the temperatures of the various components with enough accuracy, they would fall in this order, with highest temperature listed first: ambient air temperature, condensate droplets, external wall of the bottle, internal wall of the bottle, liquid in the bottle.
