the free electrons aid heat transfer, in the same way as they allow electric current to flow.
A hot bit of metal will have a lot of high energy free electrons whizzing around, which will in turn collide with other electrons and atoms, passing on their energy through the material.
In a non-metal, heat trasfer can only occur by vibrating atoms, and these do not pass on their energy as efficiently as they are limited in motion about a point.

∙ 13y agoMetals have free electrons, an electron pool infact, which heat up when the metal is heated and gain energy. This energy moves them around the metal, nd they transfer that energy to other electrons and atoms when they knock into them. Liquids also do this, but metals are the best.

Is conduction faster in metals than in other solids because metals have free electrons that transfer thermal energy?
Yes, the free electrons in metals are responsible for the high thermal conductivity.
What evidence is there to confirm band theory in solids?
There are several pieces of evidence dealing with electrical, optical, mechanical, and thermal properties of solids. To list a few:The relationship between conductivity and temperature for metals and semiconductors.The normal and quantum Hall effects.Optical absorption spectra.The elastic moduli of metals and semiconductors.
What shape and volume properties do gases and liquids and solids have?
Mass and volume
When heat energy travels through solid materials it is called?
The movement of heat through a solid is called heat conduction.
How do you convert conductivity and temperature to total dissolved solids TDS?
E. Conductivity(uS/cm) * 0.67 = TDS ppm

Yes, the free electrons in metals are responsible for the high thermal conductivity.
What determines that an element is metal?
For example the aptitude to form cations in solution. And generally metals are solids, hard, with good thermal and electrical conductivity, etc.

Do different metals conduct heat and electricity differently?
There are two main ways thermal energy is stored in solids. One way is in higher vibrational energy of the atom around its normal position and the other is in higher kinetic energy (or energy of motion) of any free electrons. In metals, heat energy is mostly transferred by the free electrons, which are free to easily move about the solid. This is why metals have the highest thermal conductivity. Here the thermal energy is picked up by the free electrons and rapidly transferred from atom to atom.
What shape and volume properties do gases and liquids and solids have?
Mass and volume
What has the higher speed of sound?
It Is solids like metals. Sound has a high speed n metals.
A property not associated with metal are electric conductivity?
Low Melting Point. Most metals have high melting point and are solids at room temperature.
When heat energy travels through solid materials it is called?
The movement of heat through a solid is called heat conduction.
Are solids a metal?
All the solids are not metals they may be non metals and other compounds but except Mercury all the metals are solids.
Are solids good source of conductivity?
Some solids are good conductors, some are not.
Do solids have thermal energy why?
Solids have thermal energy because all objects have thermal energy.
What is true about transition metals?
Transition metals are elements that also have the properties of metals. All of them have high heat conductivity, low ionization energies and high melting points. Examples of transition metals are vanadium, nickel, and zinc.
