Suppose that a (small) charged conductor is connected to the ground. Explain why the conductor becomes uncharged. Why is SO2 a gas at room temperature? Why does the solubility of gases decrease with increased temperature? Why are transition metal compounds colored?
(a) Iodine is a lustrous non-metal. (b) Bromine is a non-metal which exists as a liquid at room temperature. (c) Graphite is the allotropic form of carbon and it is a good conductor of electricity. (d) Carbon is a non-metal which is known to form t
The mixture composed of the hard poor conductor material powder 4 such as SiC, B4C, Si3N4, BN, TiN or Al2O3 and the metallic powder 5 of the binder material such as Fe metal or Ni-Sn alloy is packed on the sintered hard alloy layer 1. The punch 6 is lowered to pressurize both...
the finely divided metal burns with a brilliant light at a red heat. This can be shown by holding aluminium foil in the flame, or by blowing finely divided metal, such as is used in the form of aluminium bronze, through the flame. It takes fire, however...
