Classification og Matter and Solids
States of Matter - All matter consists of atoms and molecules. Each of these atoms and molecules has certain amount of energy. The level of this energy decides the state in which the matter exists. When heat energy is supplied to matter, this energy level rises. As a result of t..

Equilibrium Between a Solid and its Solution
The extent to which a solute dissolves in any solvent is termed as its solubility. Different substances have different solubility, some dissolve more and some less. A solution containing the maximum amount of solute at a fixed temperature and pressure is called a saturated solution. A saturated sol..

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 anode. f..

Ionic solids are hard and brittle. Ionic solids dissolve in polar solvents like water "The ions of the ionic solids are pulled out of their lattice sites by the dipole movement of the polar solvent and dispersed into solvent form in the solution. Ionic sol..
Magnetic Properties of Solids
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 electron may be consider..

More than 80 elements in the periodic table are metals. Metals are solids at ordinary temperature and pressure, with the exception (of mercury and gallium). Metals have characteristic properties such as: High thermal and electrical conductivity. Luster and high reflectivity. Malleability ..
Solid-Liquid Equilibrium
When a solid is heated it starts melting at a certain fixed temperature (melting point). At this stage even when the heating is continued, the temperature does not change until the whole of solid is converted into liquid. The state when solid and liquid phase..

Really helpful and explained things very clearly! Even though my session got over I can complete my homework myself
I liked the detailing in the explanations, and how the steps were performed. good job!
Tutor was excellent, asnwered the question rapidly and provided the information I needed to understand the problem.
I am a big fan of TutorVista tutoring. I am studying here from couple of months now and I want to continue for ever. - Ben
