Which statement best describes the energy changes associated with evaporation and boiling?

Question

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.

Answer 1

The statement that best describes the energy changes associated with evaporation and boiling is:

Atoms gain energy during evaporation and boiling.

During both evaporation and boiling, liquid molecules gain sufficient energy to overcome intermolecular forces, allowing them to transition into the gaseous state.
