Question

why is evaporation considered as a physical and an endothermic change​

Answer 1

The countless activities of everyday life are governed by the movement and transformation of energy. An electric oven takes energy from a power plant and gives it to a loaf of bread. A hammer transfers energy from arm muscles to a nail, and a falling object transforms potential energy into kinetic energy. Heat is perhaps the most familiar form of energy, and condensation is one of the countless natural phenomena that involve the movement of heat between an object and its surroundings.

Answer 2

Answer:

Explanation:

When liquid particles gain enough energy to overcome the attraction holding them together, they become a

gas. Once liquids become a gas, the molecules can move faster. Instead of sliding over each other like a

liquid, they can fly around attracted to nothing.

Molecules that are evaporating are absorbing heat. Because the molecules are absorbing heat, evaporation is called endothermic.

Remember, endo means “to enter” while thermic means “heat.”
