What happens to the temp of the liquid in a cup if water as some of the water evaporates

The correct answer is cooling effect is observed.

Explanation:

With the evaporation of some of the water, it can be said that the molecules of water have captivated heat from the environment and the liquid state of water get convert into the vapor state. Thus, a cooling effect is witnessed because the heat of the surrounding molecules has got diminished due to the absorption of the molecules of water. Therefore, there will be a reduction in the temperature and a cooling effect is witnessed.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
