Question

Processes are described as either endothermic or exotherm depending on whether energy is absorbed or lost. Cooking an egg is one type of process, while the formation of snow is another. In three short sentences, determine which process is endothermic and which process is exothermic. Explain the reason for your answer.

Answer 1

Cooking an egg is an endothermic process because it requires the absorption of heat energy to denature the proteins in the egg, causing it to solidify. In contrast, the formation of snow is an exothermic process, as it releases heat energy when water vapor in the air condenses and freezes into ice crystals. The distinction lies in the absorption or release of energy: endothermic processes absorb heat, while exothermic processes release heat.
