Ok, say you have a large cube with edges of one inch each. If you cut that cube into eight separate cubes, each with a side length of .5 inches, the surface area is increased, because now more of the original substance is exposed.

Does 1 kg of wood of sawdust have a greater surface area than one large piece of wood with a mass of 1 kg?
Surface area increases when fractionating into smaller particles. The large piece of wood will have a smaller surface area than the same mass of wood in sawdust.Example of surface area:Soils: From 1 - 800 m2 g-1, dependent to clay content.Organic matter: From 20 - 600 m2 g-1.BET is a standard method (developed in 1938) for determination of surface area together with EG (ethylene glycol) method. Both require specific particle fractioning prior to analysis and have to be carried out in a Laboratory.However, a quick an accurate DIY method is to weigh a small amount of sawdust (ideally 1g) using a kitchen scale and count the amount of particles in 1g. Then using a ruler measure the area of five particles (replicates) and calculate the average particle area by multiplying by 2 (both sides of the particle). Then multiply this area by the number of particles contained in 1g (or whichever mass previously weighed) and then extrapolate to 1 kilo.Do the same with the large piece of wood for comparison.Good luckP.A.D.V.
Does the surface of your area describe area or perimeter?
Kinda of a combination of both. The surface of a 3-D object is called surface area.
How does surface area different area?
surface area is basically the total area of each surface of the 3d object. Sa = 2-D A = 3-D
Does volume surface area have cm square?
Volume does not, surface area does.
Find the surface area of a plate?
surface area of glass plate
What happens to the surface area of a cube when the cube decreases in size?
Surface area also decreases
What happens to surface area of a tire when pressure is increased?
the surface area decreases.
What change in surface temperature occurs when there is a deficit of energy?
It increases-- The more energy in a particular space, the hotter the area.
Why does reducing solute size particle size increase the speed at which the solute dissolves in water?
For the amount of material in the particle the surface area of a small particle is greater than a larger particle. Said another way, the surface area per unit volume is greater for a smaller particle. Dissolving speed is related to the surface area. Therefore a smaller particle dissolves faster than a larger particle.
What is the tendency of liquids to decreases their surface area to the smallest size possible?
The surface area of the liquid can decrease when there is increase in the temperature of the day,what is called evaporation is been taking place in the surface of the liquid,wchich decreases the liquid area.
Can you change the rate of a chemical reaction by changing the particle size?
In hetrogeneous reactions (where the reactants are in different states) the size of the particles of a solid may change reaction rate, since the surface is where the reaction takes place, and the surface area is increased when the particles are more finely divided. In general, the smaller the particles the faster the reaction
What will happen to the loudness of a sound if the surface area of the vibrating body is decreased?
loudness is inversely proportional to the surface area so it increases when surface area decreases
What is the effect of dividing a big particle into smaller ones on the total exposed surface area?
The total surface area increases.
What happens to the surface of the cell as the volume of the cell increases?
The surface area decreases. your a lier dude
When the diameter of a sphere is decreased by 25 percent then what per cent does its curved surface area decrease?
The surface area decreases by 43.75%.
How does the surface area to volume ratio change as the cell size increases?
It decreases. As the dimensions increase by a number, the surface area increases by the same number to the power of 2, but the volume increases by the same number to the power of 3, meaning that the volume increases faster than the surface area.
Why does a cell need to divide in terms of surface area to volume ratios?
When size of cell increases ,its surface to volume ratio decreases , control of cell activities become difficult , contact area with surrounding decreases .
