What are common forensic techniques?
using aluminum powder or iodine to find fingerprints
What is the radioactive element of group 17?
Bromine (Br) is a liquid Iodine (I) is a solid
Is sublimation of iodine reversible or irreversible?
it is a physical change , sublimation is a transition of a substance from the solid phase to the gas phase without passing through an intermediate liquid phase. the iodine crystals when subject to heat turns to a violet gas , and when it cools it turns back to solid form. the composition doesn't change so it n is only a physical change
Is color a physical change?
Only if the color change is not permanent. Take Iodine for example (that's pronounced Eye-oh-deen), it is a solid metal that is grayish in color in its solid state, however in its gas state it's a purple or violet color. Once it reverts to its solid state, it turns gray again. This is a PHYSICAL property of Iodine. If the color changed permanently to something else, it would be a chemical change.
What is a good titile for my science project about are fingerprints inherited?
fingerprints
Why doesn't solid iodine stick to finger prints?
solid iodine does not stick to fingerprints because it is a solid however when it is transferred into a gas it is
Why does solid iodine only stick to fingerprints when they are heated?
because when they are heated they are sticky and they only fix to fingers
Why can gas iodine stick to fingerprints?
The gas iodine will stick to the fingerprints because they will crystallize when they come into contact with a cool surface. When heated, iodine directly changes into vapor.
Why does the solid iodine only stick to fingerprints when its heated?
because the iodine needs to make contact with the fingerprint so when it's a solid it can't do that. However when it is heated it turns in to gas (sublimation) it rises up and as it make contact with a coooler surface (the fingerprint) it crystallizes and makes it visable.
Why does solid iodine not stick to fingerprint when heated?
that is because of iodine is solid and when it heated it mulicules moves faster after that your finger prints will not be seen and even did not stick from:bloodboilz_15@yahoo.com pake add me
Explain why the solid iodine did not stick to the finger prints but it could when it was heated?
because it was a solid particle and it turned in to a liquid form when heated.
How does iodine show up the fingerprints?
dont now
Why does iodine work when using to find fingerprints?
probably because iodine sticks to the oil from your fingers
Is there a better technique than iodine to search for fingerprints?
It is simple
Is there a better substance then iodine to detect fingerprints?
no there is not a better substance
Is iodine solid a conductor?
No solid iodine does not conduct electricity.
Is Iodine a soild or gas?
Elemental iodine is a solid. But it is a volatile solid in that chemists will use solid iodine in a chamber to "iodine stain" substances in thin layer chromatography. Thus iodine is like having a volatile solid.
