you can short circuit it so that it becomes hot and literary become useless...
What ever you idiot. don't use this site again . Christopher Columbus
Create/make electrical energy.
Uhh... Fire?
Heat
This doesn't really make sense. If you apply heat to a substance you increase the kinetic energy of its particles, which we perceive as an increase in temperature.
Energy, in one form or another. Sometimes that energy is used to create a new substance, like ions coming together to make a compound, or it can also be used to create heat and light, like a light bulb with power running through it.
chemical energy
Batteries are useful because they are use to make things work and that energy is electricity.
Light energy can make heat energy
Thermal energy doesn't actually make heat. We just feel it as heat.
You cannot CREATE energy but the human body can transform energy from one kind (chemical energy in the bonds that make up food and oxygen in the air we breath) into other types of energy (heat, potential energy - by lifting something).
microwaves make heat energy
The friction between your hands create heat energy and obviously makes your hand warm.
They reduce the use of metal used to make them. (i.e. when you get disposable batteries the metal is disposed) but if you recharge batteries, it will reduce the costs of making.
Can two dead batteries make an electrical charge? Of course not! just god can CREATE a child...
There's two ways, I know one; the solar panels reflect sunlight to the top of a tower, the heat boils water to make steam and the steam spins a turbine to create energy.
the radioactive material is used to create a sustained reaction which creates heat. The heat is used to turn water into steam which turns a turbine to generate electricity.
By burning it. The heat it lets off will be energy.
