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 luck

What is a horizontal plane?
A plane is a flat surface that extends infinitely. Think of it as a piece of paper that goes on in every direction (but not "up" out of the paper). A horizontal plan just means that it extends horizontally (like a piece of paper on a desk). Another example would be the floor you are standing on or the ceiling above it. However, your monitor is - more than likely - facing up and down. That is NOT a horizontal plane.
What shape has a perimeter of 9cm?
Any plane shape. Take a piece of string and tie it into a loop of length 9 cm. Put in down on a flat surface. Then move bits of the loop in and out - every one of the shapes you make will have a perimeter of 9 cm.
Is a piece of sawdust. Bigger than a cell?
no its not!!
Does a car or a piece of paper have greater air resistance?
A car because it has a greater surface area.

Is sawdust symbolic of something?
Sawdust is symbolic of the damage and waste that is necessary in creation. In order for a piece of furniture, structure or anything to be created, there will always be consumption.
How can I create a strong and durable bond between two pieces of wood using glue and sawdust wood filler?
To create a strong and durable bond between two pieces of wood using glue and sawdust wood filler, follow these steps: Apply a generous amount of wood glue to one of the wood surfaces. Sprinkle sawdust over the glue to create a thick layer of sawdust on the surface. Press the second piece of wood onto the sawdust-covered surface, ensuring a tight fit. Allow the glue to dry completely according to the manufacturer's instructions. Sand down any excess sawdust wood filler to create a smooth and seamless finish. This method creates a strong bond between the two pieces of wood, as the sawdust wood filler reinforces the glue and helps to fill any gaps or imperfections in the joint.
Why does using powdered iron make a reaction go faster than using a single piece of iron?
It has a greater surface area than the single piece of iron
What does the mealworm need to reach adulthood?
Crumpled newspaper or sawdust and a vegetable to provide moisture like a piece of potato.
If you add a piece of hydrogen peroxide tiny gas bubbles will form. However if you crush the piece of potato first more gas bubbles will form. Explain these observations?
The crushed piece has a greater surface area, and so the reaction takes place easier and faster.
Which has the greatest density a small piece of aluminum or a large piece of aluminum?
The small piece of aluminum will have greater density than the large piece of aluminum. Density is mass divided by volume, so for the same material, a smaller piece will have more mass per unit volume compared to a larger piece.
Is a sawdust considered a mixture?
