hot glass rod

The hot saturated solution is filtered using a fluted filter paper for quick filtration, placed in a glass funnel or by hot water funnel to prevent crystallization during filtration. Filtration using a Filtration using hot waterfluted f..

It is very difficult to define, what an electric charge is? The word 'electric' is derived from the Greek word 'elektron' meaning amber. The existence of charges were known when charged particles were produced by rubbing (due to friction) of suitable materials. These facts are demonstrated by simpl..

Choose that you would like to do on a cold winter morning. => have a hot chocolate or have a glass of cold water or have an ice cream or none of these..

The rate of evaporation increases as the temperature of a liquid is increased, as it is an endothermic process. For example, a glass of hot water evaporates more rapidly than a glass of cold wate..

Two Kinds of Electric Charges - You can electrify a glass rod by rubbing it with silk. Suspend such an electrified rod by a silk thread as shown in figure. If you bring another glass rod electrified in the same manner, you will notice that the ..

Suppose it is -10 o C outside. What would you like to have? => Ice cream or A hot chocolate or A glass of cool lemonade..

A glass rod, dipped in concentrated hydrochloric acid when introduced into ammonia gas, produces thick white fumes of ammonium chlorid..

Leclanche cell of an outer glass vessel which is filled with saturated ammonium chloride (NH 4 Cl) solution. In it there stands a zinc rod and porous pot 'P' containing a carbon rod 'c' which is packed round with a mixture of manganese dioxide (MnO 2 ) and powdered ca..

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, it become..

Mirage is an optical illusion, which occurs usually in deserts on hot summer days. On such a day, temperature of air near the earth is maximum and hence is rarer or lighter. The upper layers of air, which are relatively cool, are denser. A ray of light from the top of a tree travels fro..
