# Macrostates and Microstates and their relations with Thermodynamic Probability

In this article we will define what are Macrostates and Microstates in Statistical Physics with examples and illustrations. Consider some (4, say) distinguishable particles. If we wish to distribute them into two exactly similar compartments in an open box, then the priori probability for a particle of going into any

# Statistical Physics: Ensembles

Ensembles As a system is defined by the collection of a large number of particles, so the “ensembles” can be defined as a collection of a number macroscopically identical but essentially independent systems. Here the term macroscopically identical means, as, each of the systems constituting an ensemble satisfies the same

# Rayleigh Jean’s Law

Lord Rayleigh made an attempt to explain the energy distribution in black body radiation, which was completed by Jeans in 1900. The results obtained by then are known as Rayleigh-Jean’s Rules on Black Body Radiation. The law covering these rules is called Rayleigh Jean’s Law. The black body emits radiation
