explain the process by which conduction of heat occurs
Conduction is the process of transfer of heat from the hot end to the cold end without any actual visible movement of the body.It is a process of transfer of heat mainly in solids .

In a solid ,molecules are very closely packed and can only vibrate about their mean       position .When one end of a solid is heated ,molecule at that end gain energy and start vibrating more violently .These molecules make the next to them vibrate faster .This will continue until the vibrations have been transmitted to all  the molecules and the entire body becomes hot .This is the process of conduction .
