Real-World Examples of Endothermic and Exothermic Processes
Endothermic Reactions:
Photosynthesis:
Plants use sunlight to turn carbon dioxide and water into food (glucose) and oxygen. This process takes in energy from the light, which makes it endothermic.
Dissolving Ammonium Nitrate:
When ammonium nitrate dissolves in water, it takes in heat from the environment. This causes the temperature to drop. This reaction is used in instant cold packs that help reduce swelling or cool things down.
Exothermic Reactions:
Burning Fuels:
When fuels like methane burn, they release energy. For example, the burning of methane turns it into carbon dioxide and water while letting out a lot of energy.
Respiration:
In our bodies, we convert glucose into carbon dioxide and water to release energy. This process happens every time we breathe and use energy for activities.
Interesting Facts:
By understanding these processes, we can learn about how energy moves and changes in our world!
