Chemical Energy

This is the energy which is given out when a chemical reaction takes place. This does not just happen in big things like bombs. It is happening every time we eat, use a torch, travel in a car, bus or train.

The most common chemical energy is the energy we get from food. A chemical reaction takes place in your digestive system to turn food into energy.

Similarly in a car; a chemical reaction takes place between petrol and air to give the car energy to move.

Batteries contain chemicals. Their chemical energy is changed into electrical energy when they are connected into a circuit. (BE CAREFUL! BATTERIES CONTAIN ACIDS WHICH CAN BURN YOUR SKIN, SO NEVER OPEN UP A BATTERY ).
