What happens to the Surface Area and Volume of a pyramid if the radius and height are divided by 2?
The surface area is reduced by a factor 4, the volume by a factor 8.
What happens to surface area when dimensions are changed by a scale factor?
The area changes by the square of the same factor.
How do you determine surface area of similar objects when it has a scale factor of 2?
For areas: Square the Scale Factor.

What is the relationship between surface area and dissolution rate?
In general, the dissolution rate is directly proportional to surface area. This is because the surface area tells you how much solute is exposed to the solvent. The greater the surface area, the more solute molecules that can bind to the solvent molecules, which means more dissolution.
How does surface area impact dissolution?
Surface area impacts dissolution rate by increasing the available area for the solvent to come into contact with the solute. A larger surface area means more solute particles are exposed to the solvent, allowing for a faster dissolution process. This is why powders dissolve faster than larger chunks of the same material.
Why does crushing help a solid solute dissolve?
The rate of dissolution of a solid is dependent on the surface area reaction. By crushing the cube, the surface area is greatly increased, thus increasing the rate of dissolution.
Why do we increase the why do we increase the surface area of a solid when dissolving?
We increase the surface area of a solid when dissolving to speed up the dissolution process. This is because a larger surface area allows for more contact between the solid and the solvent, leading to faster and more efficient dissolution. Additionally, increasing the surface area can also help achieve a more uniform dissolution throughout the solid.
Does surface area affect how fast a substance dissolves?
Yes, it is normal; a great surface area improve the speed of dissolution.
Suppose you were dissolving a metal such as zinc with hcl. How would the particle size of the zinc affect the rate of its dissolution?
Smaller particle size of zinc would increase the rate of dissolution due to increased surface area available for reaction. More surface area means more zinc atoms are exposed to the acidic solution, leading to faster dissolution compared to larger particles with less surface area.
What does increasing the surface area of a solid do to the solution?
Increasing the surface area of a solid can help to speed up the rate of dissolution in a solution. This is because more surface area allows for more interactions between the solid and the solvent, leading to faster dissolution.
Which has a larger surface area powder or lumps?
Powder typically has a larger surface area compared to lumps because the fine particles in powder allow for more surface area to be exposed. This increased surface area can be advantageous for processes like absorption or dissolution.
Why does crushing a solid increase the speed at which the solid dissolves?
Crushing a solid increases its surface area, allowing more solvent molecules to come in contact with the solid. This increases the rate of dissolution because it enhances the interactions between the solid particles and the solvent, leading to quicker mixing and dissolution.
Increasing the surface area between solute and solvent increases what?
Increasing the surface area between solute and solvent increases the rate of dissolution, as it provides more contact for the solute molecules to interact with the solvent molecules. This can lead to a faster dissolution process and a more efficient mixing of the solute in the solvent.
Why grinding help a solution dissolve rapidly?
Grinding increases the surface area of the solute particles, which allows for more contact with the solvent. This increased surface area facilitates faster dissolution since more solute particles can come into contact with the solvent, leading to a quicker saturation and dissolution process.
What is the surface area of salt?
The surface area of salt can vary depending on the size of the salt crystals or grains. Generally, the surface area of salt is determined by the shapes and sizes of the individual grains, which can influence properties such as dissolution rate and reactivity.
