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.
No, heat is not the best conductor. Metals like silver and copper are better conductors of heat than most other materials due to their high thermal conductivity.
In general, metals are, indeed, better conductors of heat than other materials. There is one exception, however. The best conductor of heat we know of is an allotrope of carbon we call diamond. It is many times better than the best metals at conducting heat.
it is a conductor as all other metals and the gold is also good conductor as silver!!!
No, a plate is not a conductor as it is typically made of ceramic, glass, or other insulating materials that do not allow the flow of electricity. Conductors are materials that allow electricity to pass through them easily, such as metals like copper and aluminum.
Other materials that can conduct electricity include metals such as copper, aluminum, and gold, as well as some carbon-based materials like graphite. In addition to metals, certain liquids and solutions, such as saltwater, can also act as conductors.
Mild steel is a moderate conductor of heat compared to other metals. It is not as efficient as materials like copper or aluminum for conducting heat, but it can still conduct heat fairly well in comparison to non-metals.
Its OK: most metals are good conductors -------------------------------------------- More: since a nickel is made out of copper and nickel then it is sure to be a good conductor. ------------------------------------------------------------------------ More Information: Pure nickel is not a very good thermal conductor compared to other metals like copper. Nickel is often mixed with other metals, such as copper, and those alloys often have better thermal conductivity than pure nickel.
Soil is not a good conductor of heat compared to metals or other materials with high thermal conductivity. Soil has a relatively low thermal conductivity, so it does not transfer heat as efficiently.
Energy is transfered by molecules colliding with each other. The closer the molecules are, the better they conduct energy. That is why air is a bad conductor and copper is. The molecules in copper are much closer than air molecules. Aluminum is also a bad conductor, because it is not very dense.
No. Iron is a conductor, as are the majority of other metals. Semiconductors would be like silicon and graphite in the form or carbon nanotubes. Metals = ConductorsSome metalloids=semiconductors.
Wood is not the best conductor of electricity, which means it has higher electrical resistance compared to metals. However, compared to other insulating materials like rubber or plastic, wood has lower resistance, making it a better electrical insulator.
Yes, alcohol is a thermal conductor. It has the ability to transfer heat, although not as efficiently as metals or other materials with higher thermal conductivity. It is commonly used in thermometers due to its thermal conductivity properties.
