Tungsten Metal (W) Element Chemical + Physical Properties
The chemical syol for tungsten is W which stands for Wolfram. The name came from medieval German smelters who found that tin ores containing tungsten had a much lower yield. It was said that the tungsten devoured the tin “like a wolf”. Pure tungsten metal was first isolated by two Spanish chemists, the de Elhujar brothers in 1783.

Properties of Phenol – Physical and Chemical -CoolGyan.Org
These physical and chemical properties of phenol are mainly because of the presence of the hydroxyl group in them. Phenols are much similar to alcohols but form much stronger hydrogen bonds than the alcohols. Hence, they are more soluble in water than alcohols and have a higher boiling point. Phenols occur in either the form of colourless

2 Chemical and Physical Properties of Crude Oils | Spills
The physical and chemical properties of diluted bitumen differ substantially from those of other crude oils, with key differences highlighted in Table 2-7. The distinct physical and chemical properties of diluted bitumen arise from two components: the bitumen provides the high-molecular-weight components that contribute most to density
Properties of Paper, (Paper Properties)
Moisture in paper varies from 2 - 12% depending on relative humidity, type of pulp used, degree of refining and chemical used. Most physical properties of paper undergo change as a result of variations in moisture content. Water has the effect of plasticizing the cellulose fiber and of relaxing and weakening the inter-fiber bonding.
