Energy and Biology
... The first law of thermodynamics states that energy is never lost or gained, but is only transformed. For example, in a steam engine, energy locked up in the chemical bonds of coal is transformed into heat energy and mechanical energy. There is no loss of energy in this process, but energy is transfo ...
