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 energy into the environment. This is because the heat energy from the stove causes the proteins in the egg to break down and rearrange, releasing energy in the form of heat.
The formation of snow is an endothermic process because it absorbs heat energy from the environment. This is because the water molecules in the atmosphere need to absorb energy in order to form the bonds that make up snowflakes.
