Maxwell–Boltzmann statistics

Maxwell–Boltzmann statistics Classical statistics is generally known as Maxwell–Boltzmann statistics because it got its birth from Maxwell’s law of distribution of molecular speed and Boltzmann’s theorem relating entropy and probability. The classical statistics i.e. Maxwell-Boltzmann statistics explains successfully many observed phenomenon like temperature, pressure, energy etc. On the other hand, it fails to explain certain … Read more

What is Thomson Effect

What is Thomson Effect When a current flows through an unequal heated conductor, heat is evolved or absorbed along the length of the conductor, depending on the direction of flow of current. This effect is called the Thomson effect. This effect is reversible. Consider a thick copper bar AB whose is both ends are maintained … Read more

Peltier effect definition

Peltier Effect Definition When current flows across the junctions of a Thermocouple, heat is generated (evolved) or absorbed i.e the junction gets either heated or cooled. This effect is called the Peltier effect. The condition of whether the junction shall be heated or cooled is determined by the direction of the current. Thus Peltier effect … Read more
