What else can I help you with?
What would you expect to see if the teacher puts a piece of rocksil wool soaked in Meths over a lif bunsin in burner what would you see?
If a piece of rockwool soaked in Meths is placed over a lit Bunsen burner, you would expect to see a blue flame due to the combustion of the Meths. The rockwool would likely catch fire and burn as well.
What happened when you rub an acetate rod with a dump wool?
When you rub an acetate rod with a damp wool, it causes the transfer of electrons from the wool to the acetate rod. This creates an imbalance of charge between the two materials, resulting in the acetate rod becoming negatively charged and the wool becoming positively charged. This process is known as triboelectric charging.
What new substance is produce if moisture and oxygen combined with steel wool?
If moisture and oxygen combine with steel wool, the new substance produced is iron oxide, commonly known as rust. Rust forms on the surface of the steel wool as a result of the oxidation reaction between iron, oxygen, and water.
Is rusting steel wool a physical or chemical change?
Rusting of steel wool is a chemical change because it involves a reaction between iron in the steel wool and oxygen in the air to form iron oxide (rust). This new substance has different properties than the original steel wool.
Why does steel wool corrode from water?
Steel wool corrodes from water because the water has oxygen. If the steel wool is in contact with both the water and oxygen it will begin to rust rapidly. The rusting will take a while. It will take between 5-7 days.
What are the differences between rockwool and mineral wool insulation materials?
Rockwool and mineral wool insulation materials are both made from natural rock materials, but they have some differences. Rockwool is made from basalt rock, while mineral wool can be made from various types of rock. Rockwool is denser and has a higher melting point, making it more fire-resistant. Mineral wool is generally more flexible and can be easier to install in certain spaces. Both materials provide excellent thermal and sound insulation properties.
What gives better thermal insulation glass wool or rock wool?
It depends on the application and your budget. The rockwool insulation is more dense (KG/M3) than the glasswool insulation. The rockwool is also economical as compared to glasswool insulation. In some cases where the air velocity is greater one must use rockwool because it does not decay to much and does not cause any health issues. Glasswool and rockwool, both are incombustible so you can choose whatever you want. But I shall go with the economical one.
What is the difference between aran wool and chunky wool?
which is the thicker wool, Aran or chunky
Why is rockwool insulation used?
Rock wool or mineral wool is a more compacted less friable type of molten silica (glass) wool for use as insulation it usually comes in boards or sheets of insulation from 1 to 6 inches thick. It is fairly stiff but slightly bendable it is easy to cut and shape and can be nailed or tacked into place. The heat rating and melting temperatures of rock wool are higher than fiberglass. It is usually used in industrial settings for kilns, industrial boilers, ovens and furnaces.
What are the benefits of using rockwool acoustic mineral wool insulation in a soundproofing project?
Rockwool acoustic mineral wool insulation is beneficial for soundproofing projects because it effectively absorbs sound waves, reducing noise transmission between rooms. It is also fire-resistant, mold-resistant, and easy to install, making it a durable and efficient choice for improving sound insulation in buildings.
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
What is the difference between wool and synthetic wool?
Synthetic wool is man-made; wool is cleaned, carded and spun fleece that animals grow on their skin.
What is the difference between polyester and wool?
Wool is a natural fibre grown by animals as fleece; polyester is fabricated from petroleum.
What is the difference between cashmilon and wool?
They have one common character, that is CLOTHING!
Will 000 steel wool scratch glass?
will 0000 rock wool scratch windsheild glass
When your rub a glass with a piece of wool. what happen?
Rubbing a glass with a piece of wool creates friction, causing electrons to be transferred between the two materials. The glass becomes negatively charged as it gains electrons, while the wool becomes positively charged as it loses electrons. This phenomenon is known as static electricity.
Will rubbing a glass rod with a wool cloth create static electricity?
Yes, rubbing a glass rod with a wool cloth can create static electricity by transferring electrons between the two materials. This process causes the glass to become positively charged and the wool to become negatively charged, resulting in static electricity buildup.
