Basically, any compound contains chemical energy that can be released when its chemical bonds are broken. Any substance that can be used as a fuel contains chemical energy. Examples of matter containing chemical energy include: Coal: Combustion reaction converts chemical energy into light and heat....

Anaerobic respiration is aset of chemical reactionsthat allows cells to gain energy from complex molecules without oxygen. Your muscle cells perform anaerobic respiration whenever you exhaust the oxygen being delivered to them, such as during intense or prolonged exercise. Anaerobic respiration by yeast ...
The position of these flames is dictated by a competition between the energy required to preheat the reactants, that released by combustion, and the heat lost to the wall. To model such flames, an extension to the standard 1-D, volumetric flame formulation is proposed to solve for wall/...
(c.3000bce), and to obtain iron (c.1000bce). Much of the modernhistory of technologyandsciencemight becharacterizedas a continual increase in the amount ofenergyavailable through fire and brought under human control. Most of the increased available energy has come from ever greater amounts and...

Combustion terminates whenequilibriumis achieved between thetotal heatenergies of the reactants and the total heat energies of the products. Most reactions terminate when what is called thermal equilibrium has been attained—i.e., when the energy of the reactants equals the energy of the products...
aWhat is an energy change that takes place in a lightbulb?Chemical energy changes to light energy. Chemical energy changes to heat energy.Electrical energy changes to light energy Electrical energy changes to chemical energy 什么是在电灯泡发生的能量变动?对光能的化学能变动。 对热能的化学能变动。
chemical energy, Energy stored in the bonds ofchemical compounds. Chemical energy may be released during achemical reaction, often in the form of heat; such reactions are calledexothermic. Reactions that require an input ofheatto proceed may store some of that energy as chemical energy in newly...
