Question

Processes are described as either endothermic or exothermic 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 to five 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, as it requires the absorption of heat energy to denature the proteins in the egg. This heat is absorbed from the surrounding environment, typically from the stove or water used in cooking. In contrast, the formation of snow is an exothermic process because it releases heat as water vapor in the atmosphere condenses and freezes, releasing latent heat. Thus, while cooking an egg consumes energy, the creation of snow results in energy being released.
