Question

Pumice stone is gas in solid type colloid in which dispersion phase is gas and dispersion medium is solid.
If true enter $1$ else enter $0$ .

Answer 1

Hint: Pumice, called pumicite in its powdered or residue structure, is a volcanic stone that comprises profoundly, vesicular unpleasant finished volcanic glass, which could conceivably contain gems. It is normally light shaded. Scoria is another vesicular volcanic stone that contrasts from pumice in having bigger vesicles, thicker vesicle dividers and being dull shaded and denser.

Complete answer:
We have to know that pumice is made when super-warmed, exceptionally compressed stone is savagely launched out from a fountain of liquid magma. The uncommon frothy design of pumice happens as a result of concurrent fast cooling and quick depressurization. The depressurization makes rises by bringing down the dissolvability of gases (counting water and carbon dioxide) that are disintegrated in the magma, making the gases quickly exsolve (like the air pockets of carbon dioxide that seem when a carbonated beverage is opened). The concurrent cooling and depressurization freezes the air pockets in a grid. Emissions submerged are quickly cooled and the huge volume of pumice made can be a transportation peril for payload ships.
We have to see that pumice is made out of exceptionally microvesicular glass pyroclastic with meager, clear air pocket dividers of extrusive volcanic stone. It is generally yet not only of silicic or felsic to moderate in structure, yet basaltic and different arrangements are known.
Therefore, the given statement is true. So, enter $1$ .

Note:
We have to know that pumice is usually pale in shading, going from white, cream, blue, or dark, to green-earth colored or dark. It structures when volcanic gases exsolving from thick magma structure bubbles that stay inside the gooey magma as it cools to glass. Pumice is a typical result of dangerous ejections and ordinarily shapes zones in upper pieces of silicic magmas.
