OCR: BOILING AND EVAPORATION OILING OCCURS under normal atmospheric pressure at specific temperatures, known as boiling points it causes liquids to change GAS into gases. The liquid molecules gain enough heat energy to break free and form gas. Large bubbles form in the liquid and when the pressure inside the bubbles is the same as the atmospheric pressure, boiling occurs Evaporation affects only small part of "the liquid and takes place 31 tem that are below the LIQUID liquid' boiling point occurs as the most energetic molecules on the liquid' surface escape into the air Energy ir CHANGING INTO GAS ener getic
