Qn 1: (a) Exothermic process. The heat that is released by the briquette can be felt in the surrounding. (b) Endothermic process. The water molecules must take in heat energy (increase in kinetic energy) in order to evaporate. (The skin gets cooled as water evaporates). (c) Endothermic process. The ice will take in heat energy from the warmer surrounding, causing… Read more →
