Describe
Solubility, Viscosity, luster, malleability & ductility

a gentle sheen or soft glow, especially that of a partly reflective surface.

"the luster of the Milky Way

a thin coating containing unoxidized metal which gives an iridescent glaze to ceramics.

Solubility is the property of a solid, liquid or gaseous chemical substance called solute to dissolve in a solid, liquid or gaseous solvent.

Viscosity is the state of being thick, sticky, and semifluid in consistency, due to internal friction.

Luster is a gentle sheen or soft glow, especially that of a partly reflective surface.

Malleability is a physical property of metals that defines their ability to be hammered, pressed, or rolled into thin sheets without breaking. In other words, it is the property of a metal to deform under compression and take on a new shape.

and lastly Ductility is when a solid material stretches under tensile strain. If ductile, a material may be stretched into a wire. Malleability, a similar property, is a material's ability to deform under pressure (compressive stress). If malleable, a material may be flattened by hammering or rolling.
