Endothermic and exothermic reactions happen all around us in nature. Let's break them down!
Photosynthesis: This is when plants make their food. They soak up a lot of energy—about 2800 kJ for each mole of glucose they create (that's a sugar molecule!).
Dissolving ammonium nitrate: When this chemical dissolves in water, it takes in energy (30.6 kJ for each mole). This can make the water feel colder.
Burning hydrocarbons: When we burn glucose (like how our bodies break down sugar), it releases a big amount of energy—about 2800 kJ for each mole.
Respiration: This is how our bodies use glucose to get energy. When glucose is turned into energy, it gives off around 2870 kJ for each mole.
These reactions are important because they show us how energy moves and changes in our environment, in nature, and in our everyday lives.
