First Law of Thermodynamics:
Matter and energy are relative. In a closed system, neither are created or lost. (A closed system is isolated from outside influence) “… the fundamental principle of physics that the total energy of an isolated system is constant despite internal changes”; energy changes form but does not increase or decrease qty.
ΔU = Q – W, where U = change in internal energy, Q = heat added to the system, and W = Work done by the system.
Second Law of Thermodynamics:
In the absence of outside influence, everything falls into a state of increasing disorder (entropy; biodegradation, etc.)
Third Law of Thermodynamics:
The entropy of a pure perfect crystal is zero at zero degrees Kelvin...
