When a medium or material offers a degree of resistance to a current's flow. This is usually a reference to electricity, but could also refer to heat, piping, sound, light or almost any other transfer of energy.
Any substance which does not conduct electrons well;
any non-metal.

What happens when Objects have poor conductivity?
do not transfer heat very well.
10 example of good and bad conductor of heat?
There are many uses for thermal conductivity. Thermal conductivity can be used to heat things like water and gasses are typically poor conductors.
What is the best heat insulation metal?
Metals have rather good heat conductivity and so are poor insulators but Mercury [Hg] is relatively poor on the conductivity scale. Another (relatively) poor conductor and one that is not a liquid at room temperature is Tungsten [W]. Alloys that are poor conductors include tungsten carbide (very hard too) Generally, thermal insulators are constructed with as little material as possible and inert gases or vacuum to provide insulation.
Why does a metal spoon feel cooler than a piece of wood at 20C?
Because metal has better thermal conductivity than wood. Thermal conductivity depends of the atomic and molecular structure of the stuff. The air is a poor thermal conductor, but water is better.
What is thermal and electrical conductiuity?
Thermal conductivity refers to the conductivity that is associated with heat. Electrical conductivity refers to the conductivity that is associated with electricity.
Do Ionic compounds have poor or good conductivity?
Ionic Compounds have poor conductivity when it is solid. Ionic Compounds have great conductivity when it is either dissolved in water or is melted
Do ionic compounds have poor electrical conductivity in the solid state?
poor
Is iron a poor conductor of heat and electrity?
Not a poor conductor. But conductivity is less compared to copper.
What happens when Objects have poor conductivity?
do not transfer heat very well.
What are two properties of most?
high ionization energy and poor electrical conductivity
Why do covalent solutions have poor electrical conductivity?
Covalent compounds do not dissociate into ions.
Is ionic compound electrical conductivity in the liquid state good or poor?
Good
What best explains why covalent solutions have poor electrical conductivity?
Covalent compounds do not dissociate into ions.
Do metal have poor thermal?
If you mean "thermal conductivity", no; metals are generally fairly good heat conductors.

Why does static electricity not work on picking up paper?
Wood, linen cloth and vellum{ sheepskin } all have poor conductivity .
