The density and melting point of a metal, taken together, can give a useful qualitative guide to the chemical reactivity of the metal. A high density and high melting point indicate a low reactivity; conversely, low density and low melting point indicate high reactivity. The melting point is ...
This indicates that the bismuth acts in the alloys with a density it would have at room temperature in its supercooled liquid state.doi:10.1016/0022-5088(76)90208-3Guenther H. OttoElsevier B.V.Journal of The Less-Common Metals

In fishing, the weight is made from high density materials such as metals, to make sure that it brings the hook down into the water, instead of having it float at the surface, especially when the bait is low in density and does not sink well. Fat has lower density than water and ...

A complete description of the thermodynamics of the phases of a magnetized, degenerate electron gas is obtained by calculating a generalized free energy as a function of its natural variables T , μ, H from the exact (nonanalytic) equations of state. This gives a detailed description of the ...
Gold is one of the most desired metals because of its strong physical and chemical properties. Gold has the greatest ductility of all metals, considering 30 grams can be drawn into a wire that is 80 kilometers long without breaking. Also being the most malleable, it is one of the most ve...
(YI) is a number calculated from spectrophotometric data that describes the change in color of a test sample from clear or white toward yellow. This is one of the most common tests done on plastics exposed tosterilization processes. A Hunter Lab color measurement instrument may be used to ...
