Chemical Energy

The chemical energy is the biggest source of energy employed by the man. The energy generated because of the associations of the atoms in the molecules and various kinds of aggregates of the matter results in the formation of chemical energy. It can be defined as the work done by the electric forces at the time of the re-arrangement of the electric charges, protons and electrons, during the course of aggregation.

When the chemical energy of a structure decreases at the time of a chemical retort, the difference is then transferred to surrounding areas often in the form light or heat; whereas on the other hand, when the chemical energy increases because of chemical reaction, the variation is then supplied by the surroundings normally in the form of light or heat. Paradoxically, the majority of the electricity generated globally comes from chemical energy. Especially the burning of the oil, coal and gas generates chemical energy which results in electricity. The most suitable form to store the energy is the chemical energy. The food we have, pooled with the breathing oxygen, accumulate the energy which our body extracts and change it to thermal energy and mechanical energy. The batteries are yet another example of how the chemical energy is stored, that is later regained as the electrical energy.

The relationships which we anticipate from all the forms of energy are similar to the chemical energy also. It is very important for the humans to control, master and generate the chemical energy in order to survive on the earth.
