The colors are caused by electrons that have been heated and raised to a higher energy state, and then immediately drop back down to the ground state. When the electrons drop from the higher to the lower energy states, they lose energy which is emitted as visible light and heat.
Strontium will produce different colours dependant on the circumstances. If the flame has oxygen and hydrogen present, the flame will be red. With chlorine in the flame it will be a brighter red. If it is the strontium atoms excited by themselves they produce a violet colour.
they have different electron energy levels.
because when elements are heated there electrons become excited and jump through the elements "steps" and as they become less excited the jump back down steps emitting a unique wavelength and the visible wavelength is the colour we see -------------------------------------- The wavelength of the spectral lines emitted by different elements are specific for each element. Consequently the colour is also different.
Because different elements have different energy level that their valance electrons are at and these valance electrons when subjected to energy reach a higher level where they return to the resting state energy level. While dropping back to their resting level they emit a photon of light that has a certain wavelength, different wavelengths, that the eye perceives as different colors.
No single piece of metal will produce electricity when heated. You will need two different metals, mechanically touching. When the join between the metals is heated, it will produce electricity, dependant on the metals used. This is known as a 'thermocouple'.
The color depends on the lines of the emission spectrum of each different element.
Elements emit light of specific color when heated? this is statement. what is the question?
Because each type of atom (element) has different number of electrons and different ground states , or state with out energy, so electrons will produce different colors.
the element(s) that are present in the sample
Powdered metallurgy is the process of mixing elements in powdered form and compacting them. The compacted form is then heated to form different shapes of metals.
It depends on the element being heated or frozen.
all of them, and not only the metals, all elements will become plasmas if heated enough.
I'm not too sure what you mean by 'due to the metals and non-metals' but I can tell you how the flame test actually works. Although we use this test in Chemistry to identify elements, the explanation behind it is actually physics. Basically, when an element is heated the electrons become excited, this means that they get more energy and move up an energy level or several energy levels. The electron cannot stay in this new energy level as it is unstable so it drops back down and emits the excess energy in the form of a photon. The photon has a different energy depending on which element the electrons are actually in as different elements have different energy level values. The photons have a different energy so we they must have a different frequency as E = HF (energy=Planck's constant x frequency). As different frequency of light are different colours different elements emit different frequency of photons and therefore different colours of light.
Vapor, its chemical elements do not change.
It is a spectrum produced by elements when they are heated.
The heated seat elements are located between the cushion and the seat cover.The heated seat elements are located between the cushion and the seat cover.
While some compounds do degenerate to their elements when heated, almost none do.
