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.
Tripling the radius of a sphere increases the surface area by a factor of?
9
Doubling the radius of a sphere increases the surface area by a factor of?
Four...
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 effect of reactant surface area on the reaction rate?
surface area has simple constant factor with the rate of reaction. Rate = (surface area)[concentrations with coefficients] the greater the surface area the greater the rate of reaction in a simple constant multiple.
How does the surface area affect the rate of a reaction?
The powdered solid has a greater surface area than the single lump of solid. So the larger the surface area of the solid, the faster the reaction will be. Increasing the surface area of the solid increases the chances of collision taking place between the molecules of reactants, if it is a reaction in liquid or gaseous phase.
Where surface area is not affect the rate of a reaction?
Surface area affect the reaction rate because the contact between finely divided particles is improved.
Will a smaller surface speed up a chemical reaction?
No. A smaller surface area will slow down a chemical reaction.
What factor does affect the most rate of reaction?
Factors affecting the rate of reaction 1. Temperature 2. Catalyst 3. Concentrations of the reactants 4. Nature of the reactants 5. Surface area of the reactants
How does surface area affect the weathering rates?
A great surface area is a factor which favors weathering.
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.
What happens to the greatest common factor of the cylinders' surface area if its radius is squared?
Nothing. The cylinder's surface area does not have a GCF.
A factor that affects the rate of reaction?
There are several factors that affect the rate of reaction: -The surface area available. -Temperature -Availability of catalyst. -Concentration, if a/the reactant(s) is/are solutions. -Pressure, if a/the reactants(s) is/are gases. -Reactivity of reactants. -Activation energy of the reaction.
What do concentration surface area and temperature have in common?
They can all affect the rate of a chemical reaction.
Why is surface area not factor in experiment?
It depends on the experiment!
