polarization state

A solid state cell Some electrolyte is also mixed in the cathode or anode to decrease polarization. Many solid state materials for use as cathode, anode and electrolyte have been recently developed. Some of the Li + batteries used in mobile phones are based on solid el..

London forces are the interparticle forces among the non-polar molecules such as hydrogen (H 2 ), oxygen (O 2 ), chlorine (Cl 2 ), etc., in solid or liquid states..

London Forces - London forces are the interparticle forces among the non-polar molecules such as hydrogen (H 2 ), oxygen (O 2 ), chlorine (Cl 2 ), etc., in solid or liquid states..

Electrolytes - All ionic substances and highly polar non-ionic compounds, which when dissolved in water give ions, are electrolytes. These electrolytes can be salts, acids and bases. Some of the characteristic features of these electrolytes are: They conduct electricity in their molten ..

Properties of Covalent Compounds - The covalent compounds do not exist as ions but they exist as molecules They exist at room temperature, as liquids or gases. However, a few compounds also exist in the solid state e.g. urea, sugar, etc. The melting and boiling points of covalent compound..

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 is attracted towards..

There are two overlapping water cycles operating in nature. 1) Global water cycle 2) Biological water cycle. Global water cycle does not involve life. Water evaporates from water bodies like seas and oceans (more than 75% of total evaporation), lakes and rivers. Condensation of vapour leads to prec..

The ionic crystals consist of positively and negatively charged ions arranged in a regular fashion throughout the crystal. They form a network of positive and nagative ions in three dimension in such a way that cations and anions occupy alternate sites. These are held together by strong electrosta..

. In the presence of an external electric field, the molecules align in the direction of the electric field, and is complete when working at a low temperature and stronger electric field. The "Non-polar" is that molecule in which the centre of gravity of protons (positive charge..

Water is the most abundant compound in the vast majority of cells. It forms about 60 to 90% of the total chemical content of the cell. Water accounts for about 65% of the chemical composition in the human body. In a jellyfish, the water content in the body is more than 95%! Water occurs in the..
