What are the advantages of using powdered substances rather than using solid substances?

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.

A paper is used in transferring solid substances so that we can filter the liquid substances.
How many things get turned from a solid to a liqued?
Pretty much everything, although some materials will rather go through thermal degradation instead of melting, such as trees or other organic material. Some substances will rather go from solid to gas, which is called sublimation.

Suppose you want to find the mass of a powdered solid in a small beaker. What two measurements must you make in order to obtain an accurate measurement of the solid's mass?
Measure the mass of the beaker including the powdered solid. Then empty the beaker, make sure ALL traces of the powder have been removed and measure the mass of the empty beaker. The difference between the two measure is the measure of the powdered solid.
As more substances are cooled they?
They are solid
