How are the spectra of the gasses different?

When gasses are heated they emit only certain wavelengths of light (an emission line spectrum). Different gasses emit different wavelengths. A cool object (gas or solid) can absorb some of the light passing through it. The temperature of an object is a measure of how much energy its atoms have.

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

the atomic mass is the bottom number on the element.
