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 amount of surface area of a particle compared to its mass as its size gets smaller?
As a particle's size gets smaller, its surface area-to-mass ratio increases. This is because as the particle shrinks, its volume (and therefore mass) decreases faster than its surface area. This increased surface area-to-mass ratio can influence the particle's reactivity, solubility, and other properties.
What happens to capillarity as particle size increases?
As particle size increases, capillarity decreases because larger particles have lower surface area-to-volume ratio, reducing the ability to draw in and hold water through capillary action. This is because larger particles have less surface area available for water to cling to compared to smaller particles.
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 happens to the particles if the size of the particle is increased?
If the size of a particle is increased, its surface area-to-volume ratio decreases. This can affect the particle's reactivity, solubility, and bioavailability. Larger particles may also settle faster in a suspension or have different dispersal characteristics.
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.
What reactions are affected by particle size?
Particle size can affect various reactions such as dissolution rate, surface area available for reaction, and diffusion rates. Smaller particle sizes increase the surface area, leading to faster reactions, while larger particle sizes can reduce the reaction rate due to lower surface area available for reaction.
What happens to capillary action as soil particle size decreases?
Capillary action increases as soil particle size decreases because smaller particles have higher surface area that enhances water retention and movement between them. Smaller particles create a tighter network of capillaries, allowing water to move more readily through the soil.
What is the effect of dividing a big particle into smaller ones on the total exposed surface area?
The total surface area increases.
Why does reducing solute size particle size increase the speed at which the solute dissolves in water?
Reducing the solute particle size increases the surface area available for interaction with the solvent (water), leading to more efficient and faster dissolution. This is because smaller particles have a greater surface area-to-volume ratio, allowing for more solvent-solute interactions to occur simultaneously, which speeds up the dissolution process.
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
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%.
