Question

You can get chemical energy from items listed below except

  1. Tubelight
  2. Battery
  3. Fossil fuel
  4. Food

hintHint:

Chemical Energy is Energy stored in the bonds of chemical compounds.

The correct answer is: Tubelight


    • Chemical Energy is Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic. Reactions that require an input of heat to proceed may store some of that energy as chemical energy in newly formed bonds.
    • In tubelight battery used electrical energy to emit light.
    • There is chemical energy in the battery due to the chemical reactions going on inside it.
    • Fossil fuels and food have chemical energy in them.
    • Thus, the answer is tube light.
