What will increasing the surface area of a solid do to the dissolving rate of that solid?
It will increase it, as more of the outer surface of the solid is incontact with the liquid that it is dissolving in. :)
If the surface area of a sphere is increased by a factor of 4 what is the change in the length of the radius of the sphere?
The area of a sphere is A=4*3.14 * r^2. Thus the area varies as the square of the radius. If the surface area is increased by a factor of 4, then the radius will have to increase by the square root of 4 which is 2.
The speed of a person parachuting when the surface area?
S(100)
If each edge of a cube is increased by 100 percent what is the percent of increase of the surface area of the cube?
1200 percent
What effect does the scale factor have on the area of the enlargement?
The area of the enlargement is increased by (sf)2.The area of the enlargement is increased by (sf)2.The area of the enlargement is increased by (sf)2.The area of the enlargement is increased by (sf)2.
What three factors can speed up the rate of something dissolving?
Three factors that speed up the rate of dissolution are increased temperature, increased surface area, and stirring the mixture.
How does breaking up a solid speed dissolving in liquid?
By breaking up the solid, you are creating more surface area. Therefore, increasing the surface area will speed up dissolution.
How does grinding speed up dissolving?
By grinding the surface area of the sample increase and the contact between the solvent and solute is improved.
Why does crushing a solid increase the speed at which the solid dissolves?
ALL reactions (apart from Nuclear) take place on the surface. By crushing the solid you are increasing the surface area and also the SA/Volume ratio. This increased surface area increases the area available for the dissolution reaction.
How does surface area affect dissolving?
Directly proportional
What will increasing the surface area of a solid do to the dissolving rate of that solid?
It will increase it, as more of the outer surface of the solid is incontact with the liquid that it is dissolving in. :)
How does increasing the amount of solvent speed up the dissolving process?
By breaking up the solute, the surface area between the solute and solvent is increased, meaning the solute can more easily dissolve into it's components.
Convolutions of the brain provide increased what?
The convolutions increase the surface are of the cerebrum.
How does surface area of an object affect gravity?
increasing the surface area of reactants in a solid form the speed of reaction is increased the contact between the solid reactants or liquids and gas.
How does folding the small intestine help to speed up absorption?
Increased surface area allowing for greater nutrient absorption.
Will a substance dissolve faster if it is ground into powder first?
The dissolution rate of a substance is affected by the surface area that can react with the liquid it is dissolving in. Powdering it increases the surface area so it increases the dissolving rate.
What happens to surface area of a tire when pressure is increased?
the surface area decreases.
