Exothermic and endothermic reactions in everyday life
Transcript of Exothermic and endothermic reactions in everyday life
- Energy is absorbed in an endothermic reaction, so the amount of energy in the products is higher than the energy in the reactants.
-energy is released in an exothermic reaction, so the amount of energy in the products is lower than the energy in reactants.
-Overall, exothermic reactions are a lot
more common than endothermic
reactions in everyday life. exothermic
Rusting is a chemical reaction between iron and oxygen. it is an exothermic reaction because heat is released during the reaction.
Switching on an electric light bulb
This reaction is simply an exothermic reaction where the energy released is in the form of light.
Photosynthesis is an endothermic reaction where light (energy) is required. The light is absorbed so that the plant can produce sugars and oxygen. This is the most common type of endothermic reaction in everyday life.
Mint chewing gum
When mint dissolves in water it absorbs energy. This is an endothermic reaction and this is why mint chewing gum makes your mouth feel cold.
