Answer: Chemical energy is energy stored in the structure of molecules within the bonds between atoms. Energy can be added or released from a molecule by changing the arrangement of electrons (rearranging chemical bonds).
Energy is absorbed to break bonds. Bond-breaking is an endothermic process.
Energy is released when new bonds form. Bond-making is an exothermic process.
Whether a reaction is endothermic or exothermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form.
A locations air temperature is affected by it's distance from the equator. The closer the location is to the equator, then the more energy that it will receive from the big beautiful, and hot sun.
