Detailed explanation-1: -During digestion, the chemical energy found in our food can be converted to many different forms. The chemical energy in food can be converted to another form of chemical energy when it is stored as glucose or fat. It can be converted to thermal energy because our body produces heat when digesting our food.

Detailed explanation-2: -For example, chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car’s engine.

Detailed explanation-3: -Other everyday examples of chemical energy include: Your body converts the food you eat through digestion to produce chemical energy by turning carbohydrates into glucose. Your bloodstream carries the glucose to all the cells in your body. Then, your body uses the chemical energy glucose provides.

Detailed explanation-4: -During aerobic respiration, oxygen reacts with the basic constituents of food, like carbohydrates, fats, and proteins. These are consumed as reactants to create ATP molecules. For example, ATP is produced when glucose reacts with oxygen during aerobic cellular respiration.

Detailed explanation-5: -We get chemical energy from foods, which we use to run about, and move and talk (kinetic and sound energy). Chemical energies are stored in fuels which we burn to release thermal energy-this is one way of making electricity, see Electricity for more information.
