yes it does
copper
Because of the metals and such in your blood
Metals and some ceramics.
All metals are electrically conductive.
Two different metals and a conducting fluid.
copper,gold,silver,aluminium
semi-conducting
Two different metals and a conducting fluid.
Depending on the metal, heat and electricity are two main things that metal are good at conducting.
Electrical conduction in metals nearly always (you can have conducting polymers keep in mind)
Copper, silver, and aluminum are considered some of the best heat conducting metals due to their high thermal conductivity properties. These metals are commonly used in heat sinks, electric wiring, and cooking utensils where efficient heat transfer is important.
Metals are conducting in nature because they have plenty of free electrons that can move freely throughout the material. These delocalized electrons can carry electric current due to their ability to flow easily in response to an electric field.
