What are the differences in types of wood?
cellulose content.. amount of pith..
Wood absorbing water?
Yes water does absorb into wood!
Why does a piece of wood float in water?
A piece of wood floats in water because wood has a lower density than water. This means that the weight of the water displaced by the wood is greater than the weight of the wood itself, causing it to float.
What are the differences between polyurethane oil and water-based polyurethane finishes for wood surfaces?
Polyurethane oil finishes are oil-based and provide a warm, amber tone to wood surfaces. They are durable and offer good protection against water and heat. Water-based polyurethane finishes, on the other hand, are water-based and dry clear, maintaining the natural color of the wood. They have a faster drying time, lower odor, and are easier to clean up.
What are the differences in hardness between oak and maple wood?
Oak wood is generally harder than maple wood. This means that oak wood is more resistant to dents and scratches compared to maple wood.
What are the differences between soft and hard wood?
How hard they are. And if they are from Canada or the USA.
Does a piece of wood float or sink into water?
Whether a piece of wood floats or sinks in water depends on the density of the wood. If the wood has a lower density than water, it will float. If it is denser than water, it will sink. Wood is usually less dense than water, so it typically floats.
What are the differences between oil-based polyurethane and water-based polyurethane when it comes to finishing wood surfaces?
Oil-based polyurethane and water-based polyurethane are both types of finishes used on wood surfaces, but they have some key differences. Oil-based polyurethane tends to give a warmer, amber tone to the wood and requires longer drying times between coats. It also has a stronger odor and can be more difficult to clean up. On the other hand, water-based polyurethane dries faster, has a clearer finish that does not yellow over time, and has a lower odor. It is also easier to clean up with water.
Where is water stored in wood?
Water in wood is stored in two main locations: within the cell walls of the wood fibers (bound water) and in the cell cavities or void spaces of the wood (free water). Bound water is held tightly within the structure of the wood and is more difficult to remove, while free water can be readily released as the wood dries.
Why does wood floed on water?
Wood floats on water because it is less dense than water. The spaces between wood fibers trap air, making wood less dense overall. This buoyancy force allows wood to float on the surface of water.
Does the wood float in water cause the wood has greater volume than the water?
Yes, in respect of samples of wood and water with the same weight. Before you put the wood in the water, the bulk of the water is supporting a volume of water at the surface, whose shape is the same as the submerged part of the wood. Wood has a lower density so the weight of the wood below the surface is lower than the weight of the water it displaced, and the weight of the wood above the surface makes up the difference, so the water is supporting the same total weight as before.
What is the weight of the water if one-third of the weight of the wood is above the water?
If one-third of the weight of the wood is above the water, then two-thirds of the weight is below the waterline. The weight of the water displaced by the wood is equal to the weight of the wood submerged in the water, according to Archimedes' principle. So the weight of the water displaced is two-thirds of the weight of the wood.
