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. When a substance undergoes a physical change, it does not change its identity, just its appearance. Energy is Gained and Lost. To […]
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 […]

Is current amps per second?
Is current amps per second? The SI unit of charge, the coulomb, “is the quantity of electricity carried in 1 second by a current of 1 ampere”. [10]Conversely, a current of one ampere is one coulomb of charge going past a given point per second: In general, charge Q is determined by steady current I […]
