With smaller particles there is more surface area for the solvent to reach. Less surface area means less places where the solvent can dissolve. Think about grain salt v. a salt block. If you pour the same amount of water on both, the water will reach and dissolve a majority of the grain salt immediately. However, the water will only touch the outside of the block salt. The middle would remain untouched.

∙ 14y agoDissolving takes place at the surface of the solid, increasing the surface area allows more solvent to come into contact with more solid solute. Therefore, speed of the dissolving process increases.

∙ 13y ago1. In order to dissolve, you need a solvent to do the dissolving.
2. A solvent can only dissolve what it comes in contact with.
3. When you break something into smaller pieces, its surface area increases.
4. Thus, more of the solid is exposed to the solvent.
5. Thus, more dissolving occurs per second, resulting in faster dissolvation.

∙ 12y agoI am not sure, but I would guess that the dissolving speed is limited by the solute's mantle area. In that case, it is because the smaller pieces together have a larger mantle area than the same amount in larger chunks

∙ 15y agoSmaller Crystals have larger surface area so they are easier to break down or dissolve quicked as the liquid can attack them from more space.

∙ 12y agothe smaller particles have a smaller mass than larger particles, which have a larger mass.
Wiki User
∙ 10y agoBecause relatively they have a larger surface in contact with the solvent.

∙ 8y agoThe surface area of a substance has influence on the speed of dissolution; a material as small particles have a higher area exposed to solvent.

Mixtures whose particles are smaller than those in heterogeneous mixtures and larger than those in solutions are called what?
elements
What occurs when particles in a substance move faster and occupy a larger space without changing to another state of matter?
Thermal expansion
Do bigger wheel roll faster?
No. Bigger wheels roll slower than smaller wheels. They roll slower because they have a larger circumference and they take longer to roll. Smaller wheels have a smaller circumference meaning they go faster.
How does an increase in surface area help a solute dissolve more quickly?
Not necessarily just changing the surface area causes the rate to change. Changing the ratio of surface area volume changes the rate at which a solute dissolves in a solvent. If the surface area is larger and the volume of a solute is smaller or the same, then the rate at which the solute dissolves in a solvent increases. If the surface area is smaller and the volume of the solute is larger or the same, then the rate at which the solute dissolves in a solvent decreases.
Do larger particles move faster than smaller ones?
because they have a larger mass and require a greater energy to move at the same speed. KE=1/2mv2 where m is mass, v is velocity and KE is kinetic energy so for the same energy if the mass is doubled then v2 is halved, resulting in a slower speed
How the size of particles affect the way the particles dissolve?
The smaller the particle the faster it dissolves. This is because the process by which a solute dissolves takes place at the surface of the solvent. That means the larger the surface area of a particle or solute, the faster the solute will dissolve.
What are particles that tend to dissolve faster than larger ones?
it is lighger
Does a solid dissolves faster when it is ground?
YES!answ2. Dissolution of a solid is a surface phenomenon. Smaller particles have more surface area than larger ones do. So they dissolve faster.
How does the size of the particles affect the solubility of the solute?
Particle size affects solubility. When particle size is small, the surface area per unit volume is larger, thus the solubility is increased.
Do Larger particles move faster than smaller ones and thus collide more frequently and more forcefully?
read your book. ;) but no, smaller ones move faster.
Why the water flows faster through the cylinders containing large particles than through the cylinders containing smaller particles?
because the surface area of the larger particles propels them faster which has a recipical effect on the water around the particles
Why do smaller rocks weather faster than big rocks?
Small particles weather faster than larger particles because they have a smaller surface area. For example, pebbles weather faster than boulders because the have less areas to cover.
Which statement best explains why turbigenic sediments are found in graded beds?
During deposition, larger particles usually settle to the bottom faster than smaller particles do.
Which moves faster smaller or larger gears?
Usually smaller.
Are smaller particles weathered more rapidly than larger particles?
Yes, because smaller particles are more exposed to air (large surface area).
Do smaller pieces of a solute will not dissolve as quickly as larger pieces?
no,beacause lov
Is the faster a rock cools the larger the crystals?
NO the faster a rock cools the smaller the crystals are.
