What type of energy is released during the combustion of organic molecules?

  1. Chemical

  2. Heat

  3. Kinetic

  4. Electrical

The correct answer is: Heat

This is because combustion reactions result in the release of a large amount of heat energy. While organic molecules contain chemical energy, this energy is converted into heat during combustion. Kinetic energy refers to the energy of motion and is not directly related to the combustion of organic molecules. Electrical energy requires the movement of electrons, which is not a characteristic of the combustion process.
