during which change of state do atoms lose energy?\no sublimation\no freezing\no boiling\no melting

Answer:

B. freezing

Brief Explanations:

When a substance freezes, it changes from liquid to solid. Atoms slow down and lose energy during this process. Sublimation is solid - gas transition (gaining energy), boiling is liquid - gas (gaining energy), and melting is solid - liquid (gaining energy).
