heat
A battery is a chemical source of energy that produces direct current, DC. Some are rechargeable; some are not.
Chemical energy can be used as a source of electricity through chemical reactions in batteries. When a battery is connected to a circuit, the chemical reaction within the battery generates electrical energy that can be used to power devices.
well it is a source because chemical is a gas and it is a energy with carbon dyoxide in Sid eof the gas
The source of energy for most organisms is chemical energy and sunlight.
Chemical energy
The source of energy for photosynthesis is sunlight, which is converted into chemical energy in the form of glucose. In contrast, the source of energy for cellular respiration is glucose, which is broken down to release chemical energy in the form of ATP.
Chemical Energy
The source of energy used by mitochondria is ATP.
battery
That is chemical energy. Energy is in the ATP molecules
Rocket fuels are used. It contains chemical energy
