Cooking an egg is one type of process, while the formation of snow is another. Three to five sentences, identify each as exothermic or endothermic and explain how you know.

Answer 1

Cooking an egg is an endothermic process. This is because energy is absorbed from the surroundings in order to cook the egg. When heat is applied to the egg, it absorbs the heat from the stove or pan, causing the proteins and water in the egg to denature and solidify into a cooked state.

The formation of snow is an exothermic process. This is because energy is released to the surroundings during the formation of snow. When the atmospheric temperature drops below freezing point, water vapor in the air undergoes deposition and changes directly into solid ice crystals, releasing latent heat in the process. This release of heat is what makes the surrounding air feel even colder during snowfall.
