Heat and Light energy
Chemical reactions bring about a change in matter that produces new substances. and energy is given off or absorbed.
Chemical, light is a form of energy. When energy is given away it typically is a chemical change. Ex: Fire
when they form compounds with metals or other non-metals
It depends what it is... if you were talking about a light bulb for instance.. more heat energy is given off than light.
Nonmetals, they fill out their outermost energy level by gaining electrons.
That depends on the specific situation.
It is given off
All of the energy in the battery, or most of it, is eventually given off as heat and light.
Light energy is given off by luminous objects.
Fat has the most energy given off when oxidized. About three times more than Carbohydrates. Protein gives off very little energy when its oxidized.
A flashlight is given off light and heat energy once turn on.
ALL the energy given off by the Sun travels through space because if the sun has given it out, there is nowhere else it could go. Most of the energy is electromagnetic, with its peak intensity in the visible part of the spectrum.
Yes, energy is given off when chemicals react. Since energy can be heat or light it is also given off.
