Yes; the dissolution rate is increased when a substance is as small particles.
Yes, in fact stirring does increase the rate of dissolving [or dissolution] of solids.
The higher the temperature, the greater the rate of dissolving.
How do the following factors affect the rate of dissolving for temperature change
no
A very soluble substance is dissolved faster.
In a high volume of solution dissolving is faster.
Both stirring and heating increase the rate of dissolving
Yes; the solubility of solids in liquids decrease when the temperature decrease.
depends how many bums are fighting for it, and how hungry you are
YesYes
Stirring and increasing temperature increase the dissolving rate.
