Answer:
Electrical energy to mechanical energy
Explanation:
In an electric motor, the energy transformation that is involve is a move from from electrical energy to mechanical energy.
For every system, according to the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".
- An electric motor converts electrical energy to mechanical energy
- The electrical energy passes through and electromagnet set up.
- This then cause the motion to rotate.
- Therefore, electrical energy is transformed to mechanical energy.
This chemical reaction can also be written as
2C2H6+7O2-->4CO2+6H2O
This is a chemical reaction because reactants are converted into products. This is the combustion of ethane where ethane and oxygen have been converted into carbon dioxide and water
