Vitamin B12 is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement and a prescription medication. Vitamin B12 exists in several forms and contains the mineral cobalt [ 1-4 ], so compounds with vitamin B12 activity are collectively called cobalamins.
Chemical Energy to Thermal Energy. Chemical energy is a potential form of energy that is stored in the chemical bonds that hold atoms together. If bonds are broken, the energy is released, and if bonds are formed, energy is absorbed.Thermal energy is often referred to as heat energy.uring conversions from chemical energy to thermal energy, the energy stored in the chemical bonds are released and this energy causes surrounding molecules to move faster thus increasing the thermal energy of a substance. Examples of Chemical Energy to Thermal Energy: 1. Coal is burned at a power plant.
Food, biomass, fuel and explosives have a store of chemical energy. The energy from food is released by chemical reactions in our bodies in the form of heat. Fuels like coal, oil and natural gas contain chemical energy that may be converted into other forms of energy like heat and light.n this lesson, we are going to look at the forms that energy exists, namely: heat, light, sound, electrical, chemical, nuclear and mechanical. These forms of energy may be transformed from one form to the other, usually with losses.
