Please answer the following question: Boiling means change from a liquid into a gas by adding heat energy, and boiling is the very rapid conversion of a liquid into vapor by the violent evolution of bubbles. Given these facts, what means a change from a liquid into a gas by adding heat energy among the following options: - Evaporation of water - heat is produced - violent evolution of bubbles - igniting fuel and oxidiser - Water expanding - a hemisphere is tilted away from the sun - evaporative cooling - degrees Celsius
A:
violent evolution of bubbles
