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.
Yes, the purity of a substance can affect its dissolving rate. Higher purity substances typically dissolve faster because there are fewer impurities or other substances present that might interfere with the dissolving process. Impurities can slow down the dissolving rate by creating barriers for the solvent to interact with the solute particles.
Three factors that affect the rate at which a substance dissolves are temperature, surface area of the substance, and the stirring or agitation of the solution. Increasing the temperature generally increases the rate of dissolving, while breaking the substance into smaller pieces or increasing its surface area also speeds up the process. Stirring or agitation helps to bring fresh solvent into contact with the solute, enhancing the dissolving rate.
In a scientific experiment testing the dissolving of sugar, a control group is not typically necessary. The process of dissolving sugar is a well-known and established phenomenon, so the focus is usually on the variables that affect the rate of dissolution rather than comparing against a control.
When the dissolving rate equals the rate at which molecules come out of solution, the solution is in a state of dynamic equilibrium. This means that the amount of solute dissolving is equal to the amount of solute precipitating out of solution, resulting in a stable concentration of solute.
Factors such as temperature, stirring/mixing, surface area of the solid, and the nature of the solvent can affect the rate at which a substance dissolves. Cooler temperatures, lack of stirring, smaller surface area, and low solubility of the solute in the solvent can slow down the dissolving process.
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.
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.
colour is a physical property that has no effect on the rate of dissolving
Temperature and particle size of the solid will affect both the rate of dissolving and the solubility in a liquid. Higher temperatures generally increase the rate of dissolving and solubility, while smaller particles increase the rate of dissolving due to increased surface area available for interaction with the solvent.
depends how many bums are fighting for it, and how hungry you are
Yes, the purity of a substance can affect its dissolving rate. Higher purity substances typically dissolve faster because there are fewer impurities or other substances present that might interfere with the dissolving process. Impurities can slow down the dissolving rate by creating barriers for the solvent to interact with the solute particles.
The three factors that affect the dissolving process are temperature (higher temperature typically increases the rate of dissolving), surface area (smaller particles dissolve faster), and stirring or agitation (increases contact between solvent and solute, speeding up dissolving).
