electric energy.“
„

„
If I think of an electric car, part of the chemical energy of the battery is also transformed into ...
... kinetic energy.“
... fuel.“
„
Another example comes to my mind. Plants are able to grow, because they receive energy from the sun in the form of ...
... chemical energy.“
... light.“
