The best heat-conducting metals have high thermal conductivity and are useful for many applications, such as cookware, heat exchangers, and heat sinks. On the other hand, metals with a lower rate of heat transfer are also useful where they can act as a heat shield in applications that generate large amounts of heat, such as airplane engines.

The ability to retain heat is a function of the stone's specific heat capacity and density. Another factor in choosing stone could be how quickly the stone transfers heat, called thermal conductivity. Put the stone's capacity to store heat together with thermal conductivity to find the stone that absorbs heat the best, and does it the quickest.

The heat conductivity of a material depends on its heat transfer ability, depending on the cross-section area, thickness, and temperature between a heat source and destination. Glass has seemingly very low thermal conductivity in comparison to the thermal conductivity of some daily use metals like Iron, Silver, Aluminium, and Brass.

Other metals with a high level of electrical conductivity are copper and gold. Conductivity is measured by an element's ability to transmit energy. If an element is considered to be electrically conductive, it means that it has the ability to conduct electricity.

Updated September 04, 2019. Conductivity refers to the ability of a material to transmit energy. There are different types of conductivity, including electrical, thermal, and acoustical conductivity.

For silver 00/0.24 x 100 = 4.6°C. The smaller the specific heat value, the higher the temperature change, when equal amounts of energy are added to equal amounts of mass of metal. Thermal conductivity - the ability of a substance to conduct heat (an intensive property of matter). In general, metals are good conductors are heat.

That's because the heat is conducted around by waves- mostly electron waves but also some sound waves. The variation from one type of atom to the next in an alloy makes for a sort of bumpy environment, where the waves bounce around instead of traveling a long way in one direction. So they don't conduct heat as well from one place to the next.
