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
What is surface area of cube of 12cm?
Surface area equals 864cm2
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 increases as particle size increases?
As particle size increases, the surface area-to-volume ratio decreases. This can lead to a decrease in reactivity for certain chemical processes, as fewer surface sites are available for interactions. Additionally, larger particles may settle more quickly in a fluid due to increased gravitational forces acting on them. Thus, various physical and chemical properties can change with increasing particle size.
What happens to surface area of a tire when pressure is increased?
the surface area decreases.
What is the Relationship between particle size and surface areaor the surface area per unit wt of soil?
The relationship between particle size and surface area in soil is inversely proportional; smaller particles have a larger surface area per unit weight compared to larger particles. This increased surface area enhances the soil's ability to retain water and nutrients, making fine particles, like clay, more reactive and capable of holding more nutrients than coarser particles, such as sand. Consequently, as particle size decreases, the surface area per unit weight increases, affecting soil properties such as fertility and drainage.
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?
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.
