The laws of thermodynamics are important unifying principles.
These principles govern the chemical processes (metabolism) in all biological organisms.
The laws of thermodynamics are of the utmost importance, in all scientific communities, from biology to chemistry to mechanical systems.
In all areas of scientific study the laws of thermodynamics define the parameters in which each respectively can function.
The First Law of Thermodynamics, also known as the law of conservation of energy, states that energy can neither be created nor destroyed. It may change from one form to another, but the energy in a closed system remains constant.
