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 is iodised salt better than non iodised salt?
Unless you have other sources of iodine in your diet, iodized salt is better. Low iodine can cause a wide variety of health issues. Iodine is necessary for the thyroid gland to make thyroxine hormone. In case iodine is deficient in our diet, e.g. not eating enough fish and other seafood that contains natural iodine, there is a possibility that we might suffer from goitre. Iodine deficiency can also produce mental retardation and is a global problem. Excessive use of table salt (NaCl) is also harmful, so a balanced seafood diet is better against mental and other malnutrition problems.
