How does surface area affect damping of an oscillation?
The larger the surface area, the larger the damping of an oscillation
How does surface area affect collision rate?
Surface area affects collision rate because the larger the surface area the more air resistance is acting on it, therefor a larger surface area can slow down collision rate.
Why must a substance be in the powder form before dissolving it?
The actual surface area of the substance is larger when it's in powdered form, and as dissolving only happens at the surface area, dissolving a powder is a faster process. It is not an absolute necessity , though. When the substance is not powdered, it will dissolve as well, as the amount you can dissolve is only dependent on the substance involved. However, in powdered form, it will dissolve quicker.
How do you calculate coverage of a thermosetting powder?
Calculate the surface area of the item to be powder coated. Then after finishing the production(Powder coating), find out as to how much powder is consumed and how many items are Powder coated. Then calculate the coverage in square inches per Kg of powder used as under:- Surface area of item in Square inches x Number of items Coated Powder used in Kg
Why are cristae highly folded?
To provide a larger surface area.
Which has a larger surface area powder or lumps?
A powder has a larger surface area.
Chalk reacts with hydrochloric acid when mixed Will pounding the chalk into powder increase the rate of reaction?
Yes because make the chalk into a powder increases its surface area so it is more likely to react, so rate of reaction is increased
Why does a powdered solid have a larger surface area than a solid lump?
Each speck of the powder has a smaller surface area than the lump of solid, however the total surface area of the powder specks will be greater than that of the solid lump
Does powdered or lumpy chalk have the bigger surface area?
the ratio of surface area to volume of an object is inversely proportional. that is to say, when you make the object much larger, the amount of surface area to volume goes down. when you make the object smaller, the amount of surface area compared to the amount of volume goes down. consider a cube with equal sides of 2. The volume is 2x2x2 = 8. The surface area of each side would be 2x2 = 4. Times the 6 sides ... 4*6=24. So the surface area to volume ratio would be 24 to 8, or 24/8, or 3 now make the cube smaller with equal sides of 1. Volume is 1*1*1 = 1 Surface area is 1*1 per side = 1, * 6 sides = 6. Surface area to volume ratio is 6 to 1, or 6/1, or 6. you can work it the other way too and see i'm correct. so if you take a lumpy piece of chalk and grind it into a small powder, you have taken a larger single object and made it into countless incredibly smaller objects. since you're volume is unchanged, the amount of total surface area must be much greater in the powder.
How does surface area affect damping of an oscillation?
The larger the surface area, the larger the damping of an oscillation
How does a cell's ratio of surface area to volume change as the cell grows larger?
As the cell grows larger the ratio of surface area to volume increases. Larger cell = more volume for the amount surface area.
What is the surface area of aluminum powder?
It varies depending on the particle size of the powder.
How does surface area affect collision rate?
Surface area affects collision rate because the larger the surface area the more air resistance is acting on it, therefor a larger surface area can slow down collision rate.
What surface area is larger baseball or soccer?
A soccer ball has a larger radius than a baseball, so it has more surface area.
Is true that small cells have larger surface area to volume rations than do larger cells?
Cell have a greater surface area to volume rations than a larger cell.
How does the area of exposed surface affect evaporation?
The larger the exposed surface area - the faster evaporation occurs.
How does surface area effect heat loss?
the larger the surface area you have, to more heat that you are going to lose.
