the amount is very small and unmeasureable
It affects the dissolving time because the larger it is the longer it takes and the smallest it is the less time it takess to dissolve ^___^
It depends on what you are trying to do. The solvent (can be liguid, solid or gas) is whatever dissolves another substance, the solute. If I have a heated vat of lard (melted) and want to dissolve it in some salt, then salt is the solute and the fat is the solvent. If I then pour in some vegetable fat that would be a second solute. So I would have a mixture of lard (animal fat- solvent), salt (a solute) and vegetable fat (a solute). It all depends on how the fat is being used at the time. If you are dissolving something into it; it is a solvent. If it is being dissolved into something; it is a solute.
Heating and stirring. Make sure your particle size is small.
A solute dissolves in a solvent to form a solution; all the time that more of the solute can be dissolved it is unsaturated, but once the solution can hold no more of the solute it has become saturated.
ability of a medium to attract water molecules is known as osmotic potential. you may also label it as osmotic potential. at a time a system has more water potential and low solute potential and vice versa.

A solution is a substance made after the solvent and the solute dissolved, don't be lazy next time idiot
Actually, it is not the size that matters, but the area of contact. we see that the dissolving of an object happens because there are collisions between the solvent and the solute. When the solute is BIG, for example, a block, the solvent can only collide with the surface of the block, but not the middle of the block. that means it will take a longer time for the solvent to dissolve the solute. When the block is pondered into a powdery state, it is easier for the solvent to dissolve the solute because of the larger area of collisions.
The temperature of the solution, the particle size of the solute, and whether the solution is stirred will all affect the amount of time it takes for a substance to dissolve into solution.
If the temperature of the area the dissolving solid is in is warm, the air can make the dissolving solid warm too, and eventually completely dissolve the object.
in layman's terms: when the water is hot, there is more energy and the water particles are moving faster, thus there is a higher amount of collisions per unit of time with the solute particles (the thing you are dissolving)
Dissolving time can be made faster by heating the substances.
For dissolving any solute the solvation energy of the solvent has to be more than the lattige energy of the solute. In this case the lattice energy of Nacl[salt] is more than that of sugar. Hence it takes more time to dissolve in water. ---- Akashraj Ghosh.

A greater surface area means a greater portion of the solid(solute) is in contact with the solvent at a given time. This increases the area in which interaction between the 2 substances can take place, and thus the rate at which the solute dissolves.
What factors affect the rate of dissolvingHow quickly a substance dissolves in a solvent is unknown. A teaspoon of table sugar will dissolve rapidly in a hot drink. The same amount of sugar will take much more time to dissolve in a glass of ice water. Similarly, table salt dissolves rapidly in water at room temperature. Large pieces of salt, like those used in home water softeners, dissolve much more slowly, which makes this type of salt ideal for use over long periods. The rate of dissolving is affected by three main factors:StirringTemperatureParticle SizeStirring Stirring a solution increases the rate at which a solute dissolves in a solvent. For example, you may have tried to make a soft drink by dissolving flavor crystals in a pitcher of water. The flavor crystals are the solute and water is the solvent. If the package of flavor crystals is poured into the water, dissolving begins, but clumps of powder may remain. To speed up the process, you probably used a spoon to stir the water with the flavour crystals. This results in a more uniform arrangement of flavor crystals and water particles makes dissolving occur more quickly. You can actually see the flavor crystals being stirred until they dissolve in the water. The end result is a solution, as all parts of the soft drink mixture look the same. Temperature Temperature affects the speed at which particles move. Particles move more rapidly at higher temperatures, as heat is transferred by the movement of the particles. Since the rate of dissolving depends on solute particles bumping into solvent particles, when the particles move more rapidly, more solvent and solute particles will bump into one another. In addition, the solvent particles at the edge of a piece of solute will more rapidly carry away the solute particles that they meet. This will quickly spread the solute particles throughout the solvent. With increasing temperature, most solutes dissolve more rapidly in most solvents. This explains, for example, why a teaspoon of sugar dissolves more quickly in a cup of hot tea then in a glass of iced tea.Particle Size Particle size also affects the rate of dissolving. Large particles take longer to dissolve than smaller particles of the same substance. For example, sugar cubes dissolve more slowly than granular sugar, and rock salt dissolves more slowly than table salt. Solvent particles must bump into solute particles for dissolving to occur. Particles of a solvent will contact solute particles at the surface of a clump or crystal of solute particles. Therefore, large pieces of a solute must be broken apart to enable solvent particles to come in contact with solute particles.
To speed up the dissolving of a solute you can, among many options:Heat up the mixtureStir the mixtureAdd more solute, then filter off the excessCrush the solute to give it a greater surface area
