Laws of thermodynamics

Thermodynamics is a field of research, which needs the creation of absolute and ideal states and logical and practical examination of the actual conditions. By considering all the laws and theories of thermodynamics, the chemical reactions, the occurrence of processes, and physiological functions can be predicted with this field.
