what is the relationship between particle size and specific surface area?
436870
Because surface area is the means by which a solid interacts with its surroundings, be it gas, liquid or other solids. As particle size decreases, the surface area per unit volume (or mass) increases.

Electrode Size and Current Density Electrode surface area is inversely proportional to current flow. (Larger electrode = current is less dense as it is distributed over a larger area; the smaller the electrode, the more intense the same current becomes over a smaller area.

The surface area to volume ratio of an object is the relationship between two measurements. It is the ratio of Surface area to volume. It shows the comparison between the size of the outside of an object and the amount inside. Small or thin objects have a large surface area compared to the volume.

The surface area of an (n–1)-dimensional sphere with radius r is An rn−1 and the volume of an n-dimensional ball with radius r is Vn rn. For instance, the area is A = 4π r 2 for the surface of the three-dimensional ball of radius r. The volume is V = 4π r 3 / 3 for the three-dimensional ball of radius r.

Answer. If the radius of a sphere is doubled then the surface area will increase four times. Surface Area = 4*22/7*r*r.

Difference Between Area and Surface Area. The area is the measurement of the size of flat-surface in a plane (two-dimensional) whereas surface area is the measurement of the exposed surface of a solid shape (three-dimensional). ... Also, learn difference between area and volume.

Diffusion is affected by temperature, area of interaction, steepness of the concentration gradient and particle size. Each of these factors, independently and collectively can alter the rate and extent of diffusion.

Surface area is the sum of the areas of all the faces of the solid figure. Finding surface area of solid figure is like finding how much wrapping paper that is required to cover the solid; it is the area of the outside faces of a box. ... Volume is the amount of space inside of the solid figure.

The principal parameters of nanoparticles are their shape, size, surface characteristics and inner structure. Nanoparticles can be encountered as aerosols (solids or liquids in air), suspensions (solids in liquids) or as emulsions (liquids in liquids).

Surface Areas and Volume. Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area covered or region occupied by the surface of the object. Whereas volume is the amount of space available in an object.

When an object/cell is very small, it has a large surface area to volume ratio, while a large object/ cell has a small surface area to volume ratio. When a cell grows, its volume increases at a greater rate than its surface area, therefore it's SA: V ratio decreases.

The relationship between particle size and speed it takes for the tablet to dissolve is that the smaller is the particle size of the tablet, the faster it will dissolve; or the bigger is the particle size of the tablet, the slower it will dissolve.

Surface area of cube is the sum of areas of all the faces of cube, that covers it. The formula for surface area is equal to six times of square of length of the sides of cube. It is represented by 6a2, where a is the side length of cube.It is basically the total surface area.
