How is energy transfer different from energy transformation?

• Energy transformation makes the wind to blow. Energy transfer makes metal spoons hot because of kinetic energy.

• Energy transfer makes is only for thermal energy. Energy transformation makes things move with kinetic energy.

• When energy is transferred, energy moves between molecules that are touching in a solid. When energy is transformed, energy only moves in liquids and gases.

• When energy is transferred, it stays the same kind of energy. When energy is transformed, it changes to a different kind of energy.
