glass rod art

You can electrify a glass rod by rubbing it with silk. Suspend such an electrified rod by a silk thread as shown in figure. If you bring another glass rod electrified in the same manner, you will notice that the rods repel each other..

Electric Charge - It is very difficult to define, what an electric charge is? The word 'electric' is derived from the Greek word 'elektron' meaning amber. The existence of charges were known when charged particles were produced by rubbing (due to friction) of suitable materials. These facts are dem..

Keeping in mind the structure of the atom, we can easily explain charging by rubbing. When glass rod is rubbed with silk, some of the electrons from the atoms on glass are transferred to silk. Because there is a deficiency of electrons in the glass, it ..

When a glass rod dipped in silver nitrate solution, is introduced into a test tube containing hydrogen chloride gas, a white precipitate is seen on the glass rod..

Question: A zinc rod was kept in a glass container having CuSO 4 solution. On examining, it was found that the blue colour of the solution had faded. After few days when the zinc rod was taken out of the solution, a number of small holes were noticed in it. State ..

. If a metal rod is held in the hand and rubbed with a duster, no charge is produced on the metal. Any electrons produced by rubbing can move along the metal and pass through the body to the earth. This is because our body and the metals are conductors of electricity. A metal rod..

A small piece of sodium is heated gently in an ignition tube till the sodium melts. About 50 to 60 mg of the organic compound is added to this and the tube heated strongly for 2-3 minutes to fuse the material inside it. After cooling, the tube is carefully broken in a china dish containing about 2..

Electrolysis is carried out in a specially designed apparatus called electrolytic cell. An electrolytic cell consists of a container made either of glass, or any suitable plastic material called electrolytic tank, which is a bad conductor of electricity. Two electrodes (rods or..
