Cooking an egg is one type of process, while the formation of snow is another. In three to five sentences, identify each as exothermic or endothermic and explain how you know.
Cooking an egg is an exothermic process because it releases heat. This is evident from the fact that the egg starts off raw and cold, but when heat is applied, it cooks and becomes hot. The transfer of heat from the cooking surface to the egg causes a chemical reaction, resulting in the denaturation of proteins and the solidification of the egg.
The formation of snow is an endothermic process because it absorbs heat. This can be observed by the fact that snow forms when the temperature drops below freezing, indicating that heat is being taken away from the environment. As moisture in the air cools down, it condenses and freezes into ice crystals, resulting in the formation of snowflakes. This process requires the absorption of heat from the surrounding air to provide the necessary energy for the water molecules to freeze.
