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".
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.
Because the atoms do not move around. The whole idea of convection is that 'groups' of things move about. In the case of heat convection these moving groups take or bring their heat with them.
The classical theory of solids is based on the assumption that atoms are fixed in a lattice structure and do not move. However, quantum mechanics shows that atoms in solids have wave-like properties and do exhibit movement. This discrepancy between classical theory and quantum mechanics makes classical theory inadequate for explaining the behavior of solids at the atomic level.
Yes... the transfer of energy via the vibrating molecules of solids.....
The process of conduction is how heat moves through solids. With solids, the heat energy is passed on by the 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.
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.
Heat energy can travel through solids, liquids, and gases. This means that heat can be conducted through materials like metals, transmitted through fluids like water, and even transferred through the movement of air or other gases.
it explain how we conducted our thesis
Some of the things that are commonly conducted are sound, heat, and electricity. All three of these can be conducted in any of the phases of matter, although solids and liquids are generally better conductors than gases.
the process of transfer of heat energy in solids is known as conduction.. For more info-- the process of transfer of heat energy in liquids and gases is known as convection.. And the process of transfer of heat energy without any material medium is known as radiation..
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.
Heat them.
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.
At night, there is no sun, thus there is no heat. When there is no heat, solids contract. The wires, being solids contract at night and in the morning, when there is heat, they sag.
