Thermodynamics is concerned with macroscopic processes
Statistical thermodynamics uses probability and probability distributions for large collections of particles to reproduce the same properties of macroscopic systems already established by classical thermodynamics. In so doing it can give insights into the why's of thermodynamics. Statistical thermodynamics can utilize the equations of quantum mechanics for interatomic and intermolecular forces to further explain the thermodynamic properties of macroscopic systems of real matter based on what is happening down at the atomic level.
Concept of temperature in single molecules could be explain through statistical thermodynamics and measure the temperature in term of kinetic energy of the molecules. Forclassical thermodynamics, the temperature is macroscopic properties andcan't be explain or describe in the classical scope.
What does macroscopic mean
Thermodynamics is a branch of physics and of chemistry that studies the effects of changes in temperature, pressure, and volume on physical systems at the macroscopic scale by analyzing the collective motion of their particles using statistics. via Wikipedia
examples of macroscopic system
A macroscopic cell can be seen without the aid of a microscope.
Macroscopic Observatory was created in 2009.
A germ is microscopic as well as macroscopic.
Macroscopic elements involves those changes that are observable in the environment.
A microscopic perspective, in statistical thermodynamics the entropy is a measure of the number of microscopic configurations that are capable of yielding the observed macroscopic description of the thermodynamic system:S=KBln Ωwhere Ω is the number of microscopic configurations, and KB is Boltzmann's constant. It can be shown that this definition of entropy, sometimes referred to as Boltzmann's postulate, reproduces all of the properties of the entropy of classical thermodynamics(shahbaz)
