Question

what happens when a solid is made into a fine powder​

Answer 1

Explanation:

A powder is a dry, bulk solid composed of many very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials, although the terms powder and granular are sometimes used to distinguish separate classes of material. In particular, powders refer to those granular materials that have the finer grain sizes, and that therefore have a greater tendency to form clumps when flowing. Granulars refers to the coarser granular materials that do not tend to form clumps except when wet.

Answer 2

A solid's surface area increases when it is ground into a fine powder.

• Because there are many tiny bits of the solid instead of one relatively large solid when it is crushed into a fine powder, the surface area of the solid is increased.
• As a result, the reaction can continue more quickly since there is more surface area for the other reactant to interact with.
• The reaction would proceed more slowly if the solid were ground into a fine powder than it would if it were left in one big piece because there would be less surface area to contact the second reactant.
• Compared to a solid, the powder has more surface area.

Hence, A solid's surface area increases when it is ground into a fine powder.
