Heat is conducted in solids by the speed of molecules or ionic crystals, or in the case of large molecules, the vibrations of parts of molecules. It can also be the excitement or movement of electrons in molecules or crystals.
For example when a metal, lets say copper, is heated, the loose electrons in the metallic crystal lattice move very fast within the crystal. When you touch the metal the collisions of the electrons in the metal surface causes the parts of the large molecules that make up the skin of your finger to vibrate facilitating heat exchange and "hot to the touch".
please explain
The process of conduction is how heat moves through solids. With solids, the heat energy is passed on by the atoms.
Solids do conduct heat better than gases, although not necessarily better than liquids. Some solids are actually composite materials, because they can have a porous structure which contains gas within the solid, and this results in solids that do not conduct heat very well. But it is the gas component which has this insulating property.
No. Heat is conducted from a region of high temperature to that of lower temperature. If the whole rod is at the same temperature then there is no temperature gradient and so no heat will be conducted.
you can evaporate the liquid with heat the solids will not evaporate with it
Yes... the transfer of energy via the vibrating molecules of solids.....
conduction in solids, the movement of heat in solids is sometimes called heat conduction but it can never be convectionconvection in liquids and gasesradiation
please explain
In solids, heat is transferred by conduction, the movement (vibration) of molecules. Heat transfer from solids to liquids and gases takes place through convection, or the movement of fluids at the surface. Radiation heat transfer can occur without a medium.
the heat expand the solids atoms

All objects conduct heat to some degree, even though some conduct it better than others. Objects are made out of matter, and that is the only requirement. If you want to know what an object would need to be made out of in order to conduct heat efficiently, that would be another question. Generally speaking, solids and liquids conduct heat better than gases so. Solids that contain trapped gas within them do not conduct heat as well as solids that don't.
transfer heat by fluid motion
k12? LOL solid & liquid particles are arranged closer together ;) ---> ur welcome! :P
Yes, liquids heat up faster than solids.
Heat is conducted through the air to the body.The air is a Heat conductor like steel and other materials, expect that the heat dissipates faster in air.
