In its raw form, tungsten is a hard steel-grey metal that is often brittle and hard to work. Purified, monocrystalline tungsten retains its hardness (which exceeds that of many steels), and becomes malleable enough that it can be worked easily. [21] It is worked by forging, drawing, or extruding but it is more commonly formed by sintering.

Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...

When the s.a.w. is in interval-notation, its conventional value is added too. Data is retrieved from central s.a.w. values lists, formatting is by {{Infobox element/standard atomic weight format}} (same as {{infobox element}}). Example:
