What is poly wool?
the mixture of pollster and wool is called poly wool
Is steel wool physical or chemical change?
When the steel wool burns, it is oxidized and thus this is a chemical change.
What is the specific heat capacity of rock wool?
The specific heat capacity of rock wool is typically around 0.84 J/g°C. This value may vary slightly depending on the exact composition and density of the rock wool material.
What is the difference between mineral wool and glass wool?
i feel' mineral wool is spun out of molten minerals like basalt, volcanics material, (we can also take slag wool a similar material as it comes from furnace as lawa). it is soft. glass wool have more silica in its composition,shines more and white in color ,it is brittle as compare to mineral wool .its fibre length is also more and straight as compare to mineral wool. umesh chitlangia
Is felt or fabric or wool a good insulator?
Wool is a good insulator because it has natural properties that trap air, creating a barrier against heat loss. Felt and some fabrics can also provide insulation, but they may not be as effective as wool due to their composition and density.
Why wool burns with the smell of burning hairs?
Wool is made of protein fibers that are similar to the composition of human hair. When wool burns, the sulfur-containing amino acids in the protein break down to release a distinct smell similar to burning hair. This is due to the keratin structure in wool, which is also present in hair and nails.
Is wool forming on sheep a chemical change or a physical change?
Let's call it a biological change. It has elements of both physical and chemical, but wool doesn't "form" on a sheep like, say, mold on a loaf of bread; wool is sheep hair and it grows out of hair follicles all over the animal.
What does a wool sock and a cotton shirt against each other in a dryer?
When a wool sock and a cotton shirt are dried together in a dryer, the wool sock may shrink due to its natural properties, while the cotton shirt is less likely to shrink. The differential shrinkage is due to the differences in fiber composition and structure between wool and cotton materials.
Is steel wool a good conductor of heat?
Yes, steel wool is a good conductor of heat due to its dense structure and metallic composition. When heat is applied to steel wool, it quickly conducts the heat throughout its structure, making it useful for applications like scrubbing surfaces or starting fires.
Is silk more flammable than wool and leather?
Yes, silk is more flammable than wool and leather. Silk burns easily and can catch fire quickly due to its protein-based composition, whereas wool and leather are more fire-resistant materials. Wool tends to smolder and self-extinguish, while leather is also slow to burn.
What are the three main fabric composition?
The three main fabric compositions are natural fibers (such as cotton, wool, and silk), synthetic fibers (such as polyester, nylon, and acrylic), and blended fibers (a combination of natural and synthetic fibers). Each type of fabric composition has its own characteristics and properties that affect how the fabric feels and behaves.
Is wool a homogeneous or heterogeneous?
Wool is considered a heterogeneous material. While wool fibers are made up of the same protein, keratin, the fibers themselves are not identical in terms of length, thickness, or quality. Additionally, wool can contain impurities or variations in color, making it heterogeneous in nature.
