Final answer:
The energy from the fire makes the particles inside boiling water excited and fly away.
Step-by-step explanation:
The particles inside the boiling water are excited and fly away due to the energy from the fire. When heat is applied to water, the water molecules gain energy and start moving faster. As they move faster, they collide with each other and create pressure. Eventually, the pressure becomes so high that it forces the molecules to escape as steam, causing the water to boil and the particles to fly away.
