The action that BEST demonstrates the transformation of mechanical energy to heat energy is burning a candle (Option B).
Mechanical energy refers to the energy contained by an object due to its motion and/or position. Heat energy refers to the energy caused by the movement of atoms and/or molecules.
Energy transformation refers to the process by which the energy of an object changes from one type to another.
Mechanical energy can be converted into heat energy and vice-versa.
For example, thermal (heat) energy can be used to generate mechanical energy that produces the movement of a turbine generator, which subsequently converts mechanical energy into electrical energy.
