applications of colligative properties

Colligative Properties - Certain properties of solutions depend only on the number of particles of the solute (molecule or ions) present in definite volume of the solution and do not depend on the nature of solute. Such properties are called colligativeh..

Colloidal particles have high average molecular masses. Therefore the mole fraction of the dispersed phase is very low. Hence, in colloidal solutions the relative lowering of vapor pressure, elevation in boiling point, depression in freezing point and osmotic pressure is very low. However, osmotic..

The excess pressure that must be applied to the solution/conc.solution to prevent osmosis. fig 3.11 - Principle of measuring osmotic pressure fig 3.12 If two solutions of identical composition but different concentration are separated by a semi permeable membrane (one that permits only the solvent ..

Freezing point of a substance is defined as the temperature at which the vapor pressure of the solid form is in equilibrium with liquid form of the substance. In other words, solid and liquid forms of the substance has same vapor pressure. fig 3.10 The curves AB, BC, and A'B' are the vapor pressure..

Ceramics are: Lighter, stiffer and corrosion resistant. They are brittle because of strong directional bonds. So they shatter rather than deform. The electrons in ceramics are tightly held because of covalent bonds. There are no mobile electrons to conduct current. Therefore ceramics are good..

Applications of Elasticity - Mechanical properties like strength, stiffness (Rigidity), ductility, malleability and brittleness have to be carefully studied to select a material for a particular job. The metallic parts of machines should not be subjected to stress beyond the ela..

Practical Applications of Joule's Heating - This heating is inevitable in any electrical circuit. Since the energy lost by the flowing charges ends up as disorderly thermal motion, the phrase 'ohmic dissipation' is also used to describe it. Often, this is an undesirable effect. For exampl..
