Chemical reactions can be categorized as endothermic or exothermic reactions. The reactions that gain energy are endothermic, whereas the exothermic reactions evolve heat.

The glass of lemonade is gaining energy, thus, it is an endothermic reaction.

It can be explained as:

Condensation is the process of conversion of water vapor into liquid. In the system of glass, where water is condensed is a type of phase transition. The water molecules hit the glass (cold), give up the kinetic energy, and condense into the water droplets.

Thus, the system is gaining energy and is a type of endothermic reaction.

Answer from: dbrwnn

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.
