Why will chalk dust sprinkled on a plastic sheet placed over a bar magnet NOT show the shape of the magnetic field?
Simple: chalk dust has no magnetic properties whatsoever, and is an insulator. As such, the magnetic field will flow right past it as if it weren't there, so it cannot position itself accordingly.
Is chalk magnetic?
no,chalk is not magnetic because it is not made out of either iron or steel or otherwise it is not made out of meatal
Why does an iron nail has more force of attraction than a piece of chalk and rubber band?
Because they have different magnetic properties; iron is strongly ferromagnetic.
How will you separate chalk powder iron fillings and naphthalene?
Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
What is a separation technique?
A separation technique is something used to separate an object from it's mixture. For example, in a bowl you have chalk, chalk dust, salt, and paperclips. You'd use magnetic attraction to get the paperclips out. Then you'd use your hands and take out the chalk. And then, you use a sifting tool and it'll separate the salt and chalk dust by itself. But, another cool way to separate those two is to put them in water. The salt will eventually sink because it's denser than water, and the chalk dust will float because it is less dense. Other techniques are, filteration, sifitng, magnetic attraction, evaporation, chromotography. Hope that helped! :D

How will you separate chalk powder iron filling?
Use a magnet to remove the iron filings. Filter the remainder to separate the insoluble chalk powder from the water. Wash and dry the iron filings as they will be contaminated. Dry the chalk powder to remove traces of water.

Is the chalk used in the schools magnetic?
No well i am just telling you the answer i think because i went to a school that had chalk boards.
What is the the hardest steel chalk soap wood rubber diamond plastic?
Diamond is the hardest material on the list. It ranks as a 10 on the Mohs scale of mineral hardness, making it the hardest naturally occurring substance known.

How do you separate a mixture of iron filings copper sulphate cystals and chalk powder?
Use a magnet to remove the iron filings from the mixture, then mix the remaining components with water. The copper sulfate will dissolve but the CaCO3 (chalk powder) will not. Filter the mixture to remove the chalk, then boil the water to recover the copper sulfate.
Is chalk a good insulator?
chalk is an insulator because heat does not flow through it as easily.

How is billiard chalk made?
Billiards chalk is not something that can be made at home. It is composed of an extremely fine abrasive similar to that found on very fine sandpaper. In order to make the chalk, you would have to purchase the abrasive materials. One mix that will work for the chalk is silica and corundum. This now needs to be well mixed and placed in a press or mold to compress it into the small cube.
