How long do fingerprints last on different surfaces? Fingerprints have been developed on porous surfaces (papers, etc.) forty years and later after their deposition. On non-porous surfaces, they can also last a very long time. The nature of the matrix of the latent print will often determine whether it will survive environmental conditions. How do […]

What SPDF stand for? sharp, principal, diffuse, and fundamental Why are orbitals called KLMN? The names of the electron shell were given by a spectroscopist named Charles G Barkla. He named the innermost shell has k shell because he noticed that the X-rays emitted two types energies. He noticed that K type X-rays emitted the […]
What happens to energy during a change of state why is it a physical change?
What happens to energy during a change of state why is it a physical change? A change of state is the change of a substance from one physical form of matter to another.

Why is entropy of reversible process always zero?
Why is entropy of reversible process always zero? The entropy of various parts of the system may change, but the total change is zero. Furthermore, the system does not affect the entropy of its surroundings, since heat transfer between them does not occur. Thus the reversible process changes neither the total entropy of the system […]
