Each speck of the powder has a smaller surface area than the lump of solid, however the total surface area of the powder specks will be greater than that of the solid lump
The sum of all the areas of a surface of a solid is called the 'surface area'.
9 times larger
As the volume of a cell grows, the surface area grows but not as quickly.
In my daily life, I have no use for the surface area and or volume of a cube. None whatsoever.

Powdered iron rusts more easily because the increased surface area allows for greater exposure to oxygen and moisture, which are the primary causes of rusting. The smaller particles of powdered iron have a larger surface area compared to solid iron, leading to a faster reaction with oxygen and water.
The rate of reaction increases when magnesium is in powdered form because it has a larger surface area compared to solid form. This increased surface area allows for more collisions between magnesium atoms and reactant particles, leading to a higher reaction rate.
Powdered solid fuels can burn more efficiently compared to larger solid fuel pieces because they have a higher surface area exposed to oxygen, allowing for more rapid and complete combustion. This increased surface area promotes better mixing with oxygen, leading to a more controlled and efficient burn.
Powdered soap has a larger surface area exposed to water, allowing for quicker dissolution than a bar soap that has a smaller surface area. Additionally, the powdered form is pre-dissolved and easier for water molecules to surround and break down compared to the solid structure of a bar soap.
A powdered form will generally react faster than a solid form because it has a larger surface area available for reactions to occur. More surface area allows for more contact between the substance and the reacting species, leading to a faster reaction rate.
The powdered solid has a greater surface area than the single lump of solid. So the larger the surface area of the solid, the faster the reaction will be. Increasing the surface area of the solid increases the chances of collision taking place between the molecules of reactants, if it is a reaction in liquid or gaseous phase.
A lump of solid has a much lower surface area compared to a powdered catalyst. Since most chemical reactions that are catalysed by solid phase catalysts (heterogeneous catalysts) occur on the catalyst surface more surface area = faster reaction.
If you're talking about burning, then no. Powdered aluminum has an extremely high surface area, and oxidizes very quickly. An aluminum can does not nearly the same amount of surface area, and oxidizes much more slowly, so it won't burn readily.
A substance in powder form has a larger surface area, allowing for faster dissolution as more particles are in contact with the solvent. Additionally, smaller particles in powder form have weaker intermolecular forces, making it easier for the solvent molecules to break them apart and dissolve them. This results in a quicker and more efficient dissolution process compared to larger solid pieces.
We increase the surface area of a solid when dissolving to speed up the dissolution process. This is because a larger surface area allows for more contact between the solid and the solvent, leading to faster and more efficient dissolution. Additionally, increasing the surface area can also help achieve a more uniform dissolution throughout the solid.
The advantage is that powdered substances have a much larger surface area than solids. This increased area allows more contact with reactants The speed at which chemicals will react is related to their ability to make contact with reactants. A block of iron will oxidise slowly, as the oxygen can not reach the iron except at the surface. However iron filings will oxidise much quicker because of the increased area available.
increase the surface area of a solid means to increase the area of solid
