Thermodynamics Thermodynamics is the branch of the physical sciences that studies the transfer of heat and the interconversion of heat and work in various physical and chemical processes.The study of thermodynamics is central to both chemistry and physics and is becoming increasingly important in understanding biological and geological processes. There are several subdisciplines within this blend of chemistry and physics.Classical thermodynamics considers the transfer of energy and work in macroscopic systems ;that is,…

…the distribution of the various atoms and molecules that make up the system and with energy levels of these particles.The second law of thermodynamics on the atomic and molecular level is a statistical law; it expresses a tendancy toward randomness and disorder in a system having a large number of particles. Statistical thermodynamics uses probability functions and complex mathematical methods to express thermodynamic functions in accord with the kinetic theory of matter. ------------------------------------------------------------------------ **Bibliography**
