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
Find the surface area of a plate?
surface area of glass plate
Does volume surface area have cm square?
Volume does not, surface area does.
