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. (4 points)
Cooking an egg is an exothermic process because it releases heat energy as the egg cooks. This is because the energy from the heat source is transferred to the egg, causing the proteins to denature and the egg to cook.
The formation of snow is an endothermic process because it absorbs heat energy from its surroundings. This is because the water molecules in the air must absorb energy in order to form the snow crystals.
Cooking an egg is an exothermic process because it releases heat energy. When the egg is heated, the proteins denature and coagulate, causing the egg to solidify. This release of heat is a clear indication of an exothermic reaction.
The formation of snow, on the other hand, is an endothermic process. Snow forms when water vapor in the atmosphere condenses into ice crystals. This condensation process requires the absorption of heat energy from the surroundings. As water molecules come together and freeze, they release energy in the form of heat, leaving the surrounding air colder.
In summary, cooking an egg is exothermic because it releases heat energy while the formation of snow is endothermic because it absorbs heat energy from the surroundings.
To determine if a process is exothermic or endothermic, we need to understand the concept of heat transfer. In an exothermic process, heat is released or given off to the surroundings, while in an endothermic process, heat is absorbed or taken in from the surroundings.
Cooking an egg is an example of an endothermic process. When an egg is cooked, heat from the stove or heat source is transferred to the egg, causing the proteins in the egg to denature and solidify. The heat is absorbed by the egg, making it an endothermic process.
On the other hand, the formation of snow is an example of an exothermic process. When water vapor in the air condenses to form snow, heat is released into the surroundings. This happens because as water molecules bond and arrange themselves into a solid crystalline structure, energy is released, making the formation of snow exothermic.
In both cases, we can determine if a process is exothermic or endothermic by considering whether heat is being transferred to or from the surroundings.
