Properties of Bulk Matter

Mass-Energy Relation, Mass Defect

Through precise measurement, it has been found that the mass of a particular atom is always a little less than the sum of the masses of the individual neutrons, protons, and electrons of which the atom consists. Subtracting the sum of the mass atom’s constituents from its mass, we get a mass defect ( ∆

Mass Defect

Introduction  The mass defect is a fundamental term in Physics that highlights the difference between the predicted mass and actual atomic mass, calculated by adding the neutron and proton mass in a nucleus. The predicted mass is always more than the actual atomic mass, which is calculated with the addition of nucleon masses.  Today, in

Important Topics Covering Dual Nature Of Matter

The chapter on “Dual Properties of Matter” in physics is based on the knowledge of the various properties of matter. The important topics covering dual nature of matter include various hypotheses or trials. These have been developed to show that the nature of matter can be either particles or waves. In the past, the various

Hund’s Rule

As per  Hund’s first rule, the lowest energy atomic state is the one which maximises the overall spin quantum number for the electrons in the open subshell. Before double occupation, the orbitals of the subshell are each occupied singly with electrons of parallel spin. (This is sometimes referred to as the “bus seat rule,” because it

Hooke’s Law

Hooke’s law is a law of elasticity developed by the English scientist Robert Hooke in 1660, which states that for relatively mild deformations of an object, the displacement or amount of a deformation is precisely proportional to the deforming force or load. When the load is removed under these conditions, the item returns to its

Heat, temperature, and thermal expansion

Introduction If the volume of the objects increases due to an increase in temperature, then it is known as thermal expansion. The change that occurs in volume, area, or length of an object, is called thermal expansion. In the case of a solid, linear expansion is more common. The expansion may be an increase in

Electron Binding Energy – Ionisation Energy

The more firmly bound a framework, the more grounded the powers that maintain some kind of control and the more prominent the energy expected to pull it apart. We can consequently find out about atomic powers by analysing how firmly the cores are bound. We characterise the limiting energy (BE) of a core as the
