Which statement best describes the energy changes associated with evaporation and boiling? Atoms gain energy during evaporation and boiling. Atoms lose energy during evaporation and boiling. Atoms gain energy during evaporation but lose energy during boiling. Atoms lose energy during evaporation but gain energy during boiling.

During boiling, heat is applied to the molecules/atoms of substances, and the kinetic energy of the molecules increases within the boiling container. The more the temperature, the more the kinetic energy of the molecules till the molecules at the topmost level gains enough energy to leave the rest. This is when the substance is said to have boiled.

The molecules now start leaving the surface of the boiling substance as a result of gaining enough energy. This is what is referred to as evaporation.

Hence, in both boiling and evaporation, molecules/atoms gain energy.

The statement 'atoms gain energy during evaporation and boiling' BEST describes the energy changes associated with evaporation and boiling.

In a given substance (e.g., water), atoms gain energy when they obtain kinetic energy, i.e. when they gain movement.

Evaporation refers to the physical process where a liquid is converted to a gas (in this case, water).

These processes (evaporation and boiling) increase the kinetic energy of water molecules to the detriment of the potential energy.

In conclusion, the statement 'atoms gain energy during evaporation and boiling' BEST describes the energy changes associated with evaporation and boiling.
