Uses of Silica - i) Quartz glass is used for manufacturing optical instruments. Under the trade name Vitreosil. ii) Colored quartz is used for manufacturing gems. iii) Sand is used in manufacture of glass, porcelain, sand paper and mortar etc. iv) Sand stone is used as a buildin..

1. Appearance Clear and transparent, especially in dilute form. 2. Sub-division of particles The solute breaks up into tiny particles, which could even be of ionic or molecular size. Solute particles become too small as compared to the pores of a filter paper and they pass through filter paper alon..

is the force with which a body of mass 1kg is attracted towards the centre of the Earth. 1 kg wt = 1 kg x 9.8m /s 2 = 9.8N The gravitational system is easier to comprehend and visualise than the absolute system, but the only flaw is that the value of 'g' is not a constant in all places..

Charging by Friction - Keeping in mind the structure of the atom, we can easily explain charging by rubbing. When glass rod is rubbed with silk, some of the electrons from the atoms on glass are transferred to silk. Because there is a deficiency of electrons in the glass..

The expression for acceleration due to gravity is From this expression it is very clear that acceleration due to gravity is inversely proportional to the square of the distance between the centre of the Earth and the object. That is, if the object is on the surface of the Earth it is dependent on t..

Internal energy is one of the most important concepts in thermodynamics. Energy changes in a body sliding with friction. Warming a body increases its internal energy and cooling the body decreases its internal energy. However, what is internal energy? We can look at it in various ways: let's start ..

Verification of Snell's Law - Place a rectangular glass slab on a white sheet of paper fixed on a drawing board. Trace the boundary ABCD of the glass slab. Remove the glass slab and draw a normal N 1 N 2 at O. Draw a straight line IO inclined at an angle say 30 o with ..
