Vander Waals Equation
The Van der Waals equation was derived by Johannes Diderik van der Waals in the year 1873. The equation is basically a modified version of the Ideal Gas Law which states that gases consist of point masses that undergo perfectly elastic collisions.…
Beer-Lambert Law
Who discovered the Beer-Lambert law? Pierre Bouger discovered the law in 1729. What does the Beer’s Law state? Beer’s Law or the Beer-Lambert Law states that the amount of energy absorbed or transmitted by a solution is proportional to the…
Beer-Lambert Law
The Beer-Lambert law relates the attenuation of light to the material’s properties through which the light travels. Beer-Lambert law is applied to chemical analysis measurements. Let us familiarise ourselves with the law by reading the article. What is the Beer-Lambert…
Boltzmann Equation
What is the Boltzmann equation also known as? The Boltzmann equation is also known as the Boltzmann transport equation. Who put forth the Boltzmann equation? In 1872, the great physicist and philosopher Ludwig Boltzmann put forth the Boltzmann equation. State…
Boltzmann Equation
What is Boltzmann Equation? The Boltzmann equation or Boltzmann transport equation (BTE) explains the behaviour of a fluid with temperature. It also explains the change of a macroscopic quantity in a thermodynamic system, such as energy, charge or particle number.…
Hubble Law
What is Hubble’s law used for? Hubble’s law is used for understanding the motion of astronomical objects due to the expansion of the universe. This was first used for studying the expansion of the universe and is used as the…
Hubble Law
What is Hubble’s Law? Hubble’s law statement is given as The velocity of the galaxy, which is also known as the redshift, is directly proportional to its distance. Hubble’s law is also known as Hubble-Lemaitre law, studied in physical cosmology.…
Law of Conservation of Mass
The law of conservation of mass states that mass within a closed system remains the same over time. Discover more about the law of conservation of mass, including its importance, equations, and some examples of this law in action. What…
D Alembert Principle
What is D’Alembert’s Principle? D’Alembert’s principle states that For a system of mass of particles, the sum of the difference of the force acting on the system and the time derivatives of the momenta is zero when projected onto any…
