the amount of space the substance takes up
Temperature affects the solubility of a substance but does not necessarily influence the rate at which it dissolves. For many solids, an increase in temperature generally increases solubility, allowing more of the substance to dissolve in a solvent. However, the rate of dissolution can be affected by factors such as agitation or particle size, which do not change with temperature alone. Thus, while solubility may increase with temperature, the dynamics of how fast a substance dissolves can remain constant.
Temperature affects both the solubility of a substance and the rate at which it dissolves. Higher temperatures generally increase the solubility of most substances and also speed up the dissolution process by providing more energy for the particles to overcome intermolecular forces.

Shaking affects the rate at which a solute dissolves because it increases the molecular activity of the solute within the solvent. When the molecular activity is increased, the rate of dissolving is also increased.
Factors that affect the rate at which a substance dissolves include temperature (higher temperatures usually increase the rate of dissolution), surface area (smaller particles dissolve faster), agitation (stirring or shaking the solution speeds up the process), and the presence of a solubility-enhancing solvent.
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.
Factors that can increase the rate at which a substance dissolves in water include increasing the temperature of the water, crushing or grinding the substance into smaller particles, stirring or agitating the mixture, and increasing the surface area of the substance by breaking it down into smaller pieces.
Colder temperatures make molecules move more slowly. Since molecules are moving more slowly, they are less likely to 'bump' into each other and interact. When you are trying to dissolve a substance, you want as many interactions as possible between the substance you want to dissolve and the liquid you are trying to dissolve it in. Since the cold temperature slows down the rate of these interactions, it slows down the rate at which a substance dissolves.
Reducing particle size results in an increase in surface area. The increase in surface area allows more solvent (water) molecules to interact with the substance, and this increases the rate at which that substance dissolves.
Yes, the presence of another substance can affect the rate of diffusion. Factors like the nature of the substance, concentration gradient, temperature, and molecular size can influence how quickly a substance diffuses in a system.
Decreasing temperature would not increase the rate at which a solid dissolves
