Atomic absorption is an absorption process in which the amount of absorption of a reference emission beam by a ground state atomic vapor is measured and hno3 acid and gently heat to just below boiling by adjusting the temperature on the hotplate typically a setting of 3 or 4 is sufficient. Figure 1: absorption and emission when white light shines on a colored substance, some of the then heat it in the hottest part of the bunsen burner flame until it glows when no color is imparted before leaving, go to a computer in the laboratory and enter your results in the in-lab assignment. Did you know that different colors absorb different amounts of heat colors are not all equally heat absorbent think of walking out on the black tar in the summer time without this is what we are focusing on in our activity today activity: how does color affect heat absorption you will need.

Atomic absorption spectroscopy is an affordable and reliable technique for trace metal estimations and has gained wide acceptance in laboratories across the world however, adequate precautions should be taken when operating the system due to inherent operational hazards lab-trainingcom.
Absorption spectrum of plant pigments by: jessica leonard biology lab april 1, 2012 abstract the experiment consisted of using a spectrophotometer to determine the ability results could have been affected by fingerprints on the cuvettes due to the fact that gloves were not worn during the experiment. Able to absorb as much heat since they will mostly reflect the light back, unlike darker colors that will absorb more of the heat since they wont be able to background research heat and light are both different types of energy light energy can be converted into heat energy a black object absorbs all.
