For marks in IGCSE 0625, you must state: evaporation is a cooling process where *more energetic* particles escape the liquid; conduction transfers thermal energy through *vibrating* particles in solids; gas pressure is caused by *colliding* particles exerting force on the container walls. But, mone, I see students lose marks by just parroting "particles move" without those specific, active verbs. Every morning, watching my appam batter puff up, I think how heat makes those tiny bubbles *expand*—it’s the action, not just the actors, that tells the real story.
