Question
What do the spectral lines represent?
Answer:
Spectral lines is defined by quantum mechanics in terms of energy levels of ions, molecules, and atoms. When electrons move from a higher level to lower one, photons are emitted and an emission line can be seen in the spectrum. As electrons jump down to the n=2 orbit, they emit photons of specific frequency (hence colour) that can be seen as emission lines in the visible part of spectrum.
Explanation:
When a substance goes from 1 state of matter to a another state of matter, the process is a change of state. What i found out is that it can be heated, whenever the substance goes to another phase i mostly heard, and reasearched that it goes to heated.
Well, depending on the charge, it could be Cu; if it has a charge of 2+
