help me im in science i dont know the answer
Foam is not a good conductor; in fact, it is an insulator. Foam is made up of many small pockets of gas trapped within a solid or liquid material, which greatly hinders the flow of electric charge, making it a poor conductor of electricity.
Steel is a good conductor of electricity because of its crystal structure that allows electrons to move freely throughout the material. This enables the flow of electric current with little resistance, making steel an efficient conductor for practical applications.
No, gas is not a good conductor of heat. Gases are poor conductors of heat because their molecules are widely spaced and they do not have a fixed structure like solid materials that allow for efficient heat transfer.
Magnesium chloride is not a good conductor of electricity in its solid form. However, when dissolved in water, it can conduct electricity because it dissociates into ions, which are able to carry electric charge.
No, krypton is not a good conductor of heat. It is a noble gas with very low thermal conductivity due to its monatomic structure, which limits the transfer of heat energy through the material.
fabric
No, the element sulfur (S) is not shiny and is not a good conductor of heat. Sulfur is a non-metal and is typically a yellow, brittle solid at room temperature. It is a poor conductor of heat due to its molecular structure, which does not allow for efficient transfer of thermal energy.
The metal lead. Solid at room temps, low melting point, good conductor of heat and electricity.
Graphite is a good conductor of heat due to its unique structure. The arrangement of carbon atoms in graphite allows for the easy movement of electrons, which helps to transfer heat energy efficiently throughout the material. This high thermal conductivity is what makes graphite a valuable material for applications where heat dissipation is important.
A material which is a good conductor of electricity or heat.
a metal
Glass is an example of an amorphous material because it lacks a regular, repeating atomic structure. This results in a disordered arrangement of atoms, giving it a non-crystalline, non-ordered nature.
