The entropy of a substance is a real quantity, just like pressure, volume and temperature. Its unit is joule/Kelvin (J/K).

A crystal is a solid whose constituent atoms, ions or molecules are closely packed in a regular fashion with repeating pattern in three dimensions.

Nanotechnology is dealing with the characterization, design, production and various applications of nanostructures and nanosystems.

Nanotechnology have considered as the solution to our smallest to biggest problems. Applications of Nanotechnology are countless.

Ampere’s circuital law is one of the general laws of magnetism. This law used to find the magnetic field due to current distribution.

Thermodynamics is the branch of physics which deals with heat and other forms of energy and also gives relationships between them.

Drude and Lorentz gave classical free electron theory of metals theory in 1900. Another name for this is Drude –Lorentz theory of metals.

Faraday’s law gives the idea about how an electromotive force comes into action when a magnetic field interacts with an electric circuit.
