1 Vitamins and minerals (including antioxidants, such as vitamin A, C, E and selium). 2  Vitamins and minerals are found in all foods, but fruits and vegetables are a particularly good source for some vitamins and minerals.( 3 See below for What vitamins and minerals do.).itamins and minerals are found in most foods, but fruits and vegetables are particularly good sources of many of these valuable compounds.Vitamins and minerals play a vital role in most metabolic processes. Complex interactions make it essential that the status of all vitamins and minerals be kept at optimal levels.
1 Osmium. The densest naturally occurring element on the planet is osmium, a metal in the platinum family with a density of 22.6 grams per cubic centimeter. If that means nothing to you, then youâre normal. By comparison, lead is 11.3 grams per cm cubed.
Since equal volumes of each liquid was weighed, the one that weighed the most is the most dense and the one that weighed the least is the least dense. A density tower From weighing the liquids, the relative densities of the liquids are known: Corn syrup is the most dense; Vegetable oil is the least dense; Water is in between. Carefully pour the liquids in a clear plastic cup from most dense to least dense. The liquids will float or sink on one another based on their densities.
