When water condenses on the side of your glass of cold lemonade is it a endothermic or exothermic reaction?

And why?

Exothermic is a way of giving of heat energy and condensation is a process were water vapor turns into a liquid. This occurs when water vapor molecules come into contact with cooler molecules. This causes the water vapor molecules to lose some energy as heat.

It is an endothermic process because the glas of lemonade is gaining energy.

Explanation:

The condensation of water is not a reaction, because the water is not changed into something else. We should call what's happening a process.

The glass of lemonade is the system, and the rest of the universe is the surroundings.

When the water molecules in the atmosphere hit the sides of the cold glass, they give up some of their kinetic energy and condense into droplets of water.

The system is gaining energy from the surroundings, so the process is endothermic.
