It certainly does for two reasons.
1. Friction. moving the livesaver across you tongue can be thought of as moving you knee across some pavement. What happens? you lose skin. when you just sit your knee on the pavement your skin holds up pretty good.
2. Acid density, as the lifesaver dissolves the concentration of your mouths acids get diluted and decrease around the live saver. by moving the livesaver you are subjecting it an area of the mouth that with a high concentration of acids.
Both stirring and heating increase the rate of dissolving
The bigger the particle the lesser the dissolution.
It increases the rate at which the solute dissolves.
Ill answer it, yes because mud would keep it from mixing and dissolving
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in 'equilibrium'.
yes,in fact it does.I tried an experiment and for some reason, the purple lifesaver and the white one were the last to dissolve.
The higher the temperature, the greater the rate of dissolving.
Yes, in fact stirring does increase the rate of dissolving [or dissolution] of solids.
How do the following factors affect the rate of dissolving for temperature change
no
Yes; the dissolution rate is increased when a substance is as small particles.
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
depends how many bums are fighting for it, and how hungry you are
Stirring and increasing temperature increase the dissolving rate.
