dielectric properties of solids

Dielectric Properties of Solids - Insulators do not conduct electricity because the electrons present in them are held tightly to the individual atoms or ions and are not free to move. However when electric field is applied polarization takes place because the nucleus ..

Insulators do not conduct electricity because the electrons present in them are held tightly to the individual atoms or ions and are not free to move. However when electric field is applied polarization takes place because the nucleus is attracted towards cathode and electron cloud towards an..

Properties of solids have been exploited for various new innovations in electronic and magnetic devices like transistors, computers, telephones etc. Properties of the solids mainly depend upon their structure and composition. Three main properties a..

Magnetic Properties of Solids - The magnetic properties of materials are a consequences of magnetic moments associated will individual electrons. The magnetic moment of an electron is due to its orbital motion and also due to its spin around its own axis. A moving elec..

The magnetic properties of materials are a consequences of magnetic moments associated will individual electrons. The magnetic moment of an electron is due to its orbital motion and also due to its spin around its own axis. A moving electron may be considered to be a small current loop, g..

1) Ammonium sulphate is a colourless crystalline solid. 2) It is soluble in water to a great extent. The solubility of this salt in water is 78 g at 30 o C. 3) When dissolved in water it absorbs heat and causes coolin..

Sodium hydrogen carbonate is a white crystalline solid having a density of about 2.2 g/mL It has alkaline taste and is sparingly soluble in water. The solubility of sodium hydrogen carbonate increases with the rise of temperatur..

1) Ammonium Nitrate is a colourless crystalline solid. 2) It is highly soluble in water. Its solubility in water is 242 g at 30 o C. 3) When heated, it melts and then decomposes to give nitrous oxide and water. It explodes when heated...

1) Ammonium chloride is a colourless crystalline solid. 2) It is fairly soluble in water. Solubility of ammonium chloride in water is 41.4 g at 30 o C. 3) When it is dissolved in water, it absorbs heat and causes cooling. 4) When heated it undergoes dissociation to give ammonia and hydro..

1) It is a crystalline solid. 2) It is soluble in hot water, ethanol and ether. 3) HgCl 2 reacts with KI and forms a colorless solution known as Nessler's reagent. ..
