Oh, what a lovely question! Mercury is a very special element - it's a conductor of electricity. Just like a happy little stream flowing through the forest, electricity can move easily through mercury. It's like nature's way of connecting things together in a beautiful, conductive dance.
Wood is an insulator.
Glass in a molten state is a conductor of electricity. When glass turns to a solid state it becomes an insulator.Basically, glass in a window or a test tube would be the solid state and so it is a insulator of electricity.
Cotton wool is not a conductor or an insulator it is a semi conductor. It is sort of in the middle, electrons can travel through cotton wool but not as good as silver, bronze, metal and so on.
Insulation is keeping the heat inside, trapping it and not letting out. Conduction is letting a flow, such as electricity, pass through the material. for example, metal is a wonderful conductor of heat and electricity, but a bad insulator. However, wool is a good insulator and a bad conductor. :) hope that helps!
No, oxygen is not a conductor of electricity because its in the air.
Mercury is a conductor of electricity. It is a metal with high electrical conductivity, so it does not act as an insulator.
An insulator.
A matchstick is an insulator of electricity because it is made primarily of wood, which is a poor conductor of electricity.
conductor
Toothpaste is an insulator. It does not conduct electricity well because it is not a good conductor of heat or electricity.
A seashell is typically considered an insulator because it does not easily conduct electricity. The material of the seashell is not a good conductor of electricity due to its high resistance.
Paper is an insulator of electricity.
Wood is an insulator.
An insulator for heat and (less so) for electricity. A conductor for sound and vibration.
Brass will conduct both electricity and heat. So brass is a conductor, but not an insulator.
Insulator
No because it is a good conductor of heat and electricity!
