In any energy transformation energy is preserved.
A change from one form of energy into another is called energy transformation.
Energy transformation
The radio signal itself, of course, is not an energy transformation - energy transformation means that energy is changed from one type to another. There is an energy transformation when the radio signal is created, and another one when it is absorbed.
Well, if you have electricity, and you want light, then you need to turn electricity into light, which is one kind of energy transformation. If you have chemical energy as in gasoline and wants to go somewhere, you need to turn chemical energy into kinetic energy, and maybe some potential energy as well to get anywhere.
In any energy transformation energy is preserved.

that is very important to them that what we need to learn about
Energy Transformation is when energy changes from one form to another. :)
A change from one form of energy into another is called energy transformation.
Energy transformation from a nuclear power plant
Sublimation is an endothermic phase transition.Sublimation is the transformation of a solid in a gas, directly, and need energy for this.
Energy transformation
The radio signal itself, of course, is not an energy transformation - energy transformation means that energy is changed from one type to another. There is an energy transformation when the radio signal is created, and another one when it is absorbed.
energy transformation is ruled by energy conservation. For example, potential energy may transform to kinetic energy but the sum of both remains constant before and after transformation.
