air conduction and bone conduction

If you leave the end of a metal poker in the fire for some time, its handle will get hot. Energy is transferred from the fire to the handle by (thermal) conduction along the length of the poker. The amplitude of vibration of the atoms and electrons of the poker near the fire becomes relat..

Metals are good conductors because they have free electrons. Silver is the best conductor of heat and electricity. Lead is the poorest conductor of heat. Bismuth, mercury and iron are also poor conducto..

They are poor conductors of heat and electricit..

It is defined as the conductance of that volume of solution which has one equivalent dissolved in it. ..

It is the ease provided by a solution to the flow of current...

Specific conductance Equivalent or molar conductance The difference between the two has been clearly explained. Measurement of conductance is done using Wheatstone bridge method. The difference for electrolytes are: A.C. Source is used to prevent electrolysis Earphone..

In solution or in their molten states, ions become free to move. On applying an electric field,the ions get drifted towards towards their respective electrodes.Thus, ionic compounds are good conductors of electricity in these states. However, these do not conduct in their solid state bec..

It is the reciprocal of specific resistance. It is the conductance of a solution of 1 cm length having 1 square cm as area of cross section. fig 5.2 Specific conductance depends upon the concentration of the solutio..

Conduction in Metals - Electrons become free to move throughout a crystal when they are excited to a higher energy level within the band. If the highest energy band that is occupied is not fully filled, electrons may be excited from lower energy level to higher energy level by supplying a..

If one end of a metal rod is placed in a stove, the temperature of the other end increases gradually. Heat is transferred from one end of the rod to the other end. This transfer takes place due to molecular collisions and the process is called heat conduction. The molecules at one end of ..
