Does hot glue conduct electricity?
There is one special glue that will conduct electricity. I can't remember the name, but it was an epoxy made to repair the rear window heating strips in cars in the '60's. - No other modern commonly available glues conduct.
Which non metal is most conductive?
Anything with ions really, metals conduct between they have free electrons. So water with salt, really hot gasses, etc. The more ions, the more it will conduct.
What is the element Copper used for?
Electricity cables as it conducts electricity well & hot water vessels & pipework as it is a fairly inert metal.
Can metals be bent and hammered into shape?
yes metals can be shaped with a hammer because metals ate not brittle.
Why do most metal saucepans have non-metal handles?
Because metals tend to be very effective at conducting heat. As such a metal handle will tend to get very hot as the pan gets hot. Obviously this increases the risk to the user, so saucepans commonly have handles made of a material that is a poor conductor of heat.

Can hot water conduct electricity?
Not pure water - salt water can - hot or cold.
Why does a metal spoon handle gets hot in soup but a plastic spoon handle does not?
Because metals conduct heat really well. Plastics conduct only a little heat with difficulty.
Does a glass get hot when you put hot water in it?
Glass conducts electricity well letting the heat flow through it. 2. OOPS! (it is only at very high temperatures that glass conducts electricity, and even then it is not a good conductor.) And glass is not a very good conductor of heat, but it will conduct heat albeit slowly.
Why can lead conduct heat?
All metals conduc heat; two theories were involved for the explanation:- heat conduction by hypothetic phonons (excited states in metals structures) in metals- heat conducton by "hot" electrons moving in metals

Why are metals good at conducting electricity?
Metal particles are held together by strong metallic bonds, which is why they have high melting and boiling points. The free electrons in metals can move through the metal, allowing metals to conduct electricity. Metal is a good conductor because it absorbs heat easily. Whether hot or cold.
Why does molten sodium chloride will conduct electricity?
No, it is not. 'Solid sodium chloride doesn't conduct electricity, because there are no electrons which are free to move.' http://www.chemguide.co.uk/atoms/structures/ionicstruct.html
Can hydrogen conduct electricity?
Hydrogen has the highest thermal conductivity of any gas. The electrical conductivity of hydrogen varies according to temperature. If it is cold enough, it can be a superconductor. If it is hot enough, as a plasma, it is highly conductive.
Does a wax candle conduct heat well?
If one end of a candle is very hot, with the other end feel hot? That is your answer.
Is a dog a conductor or insulater?
Most living beings conduct electricity rather well, because of the water content.Pure water is not a good conductor, but most water that occurs in nature is not pure (as in "distilled"); it has enough dissolved ions to be able to conduct electricity.Most living beings conduct electricity rather well, because of the water content.Pure water is not a good conductor, but most water that occurs in nature is not pure (as in "distilled"); it has enough dissolved ions to be able to conduct electricity.Most living beings conduct electricity rather well, because of the water content.Pure water is not a good conductor, but most water that occurs in nature is not pure (as in "distilled"); it has enough dissolved ions to be able to conduct electricity.Most living beings conduct electricity rather well, because of the water content.Pure water is not a good conductor, but most water that occurs in nature is not pure (as in "distilled"); it has enough dissolved ions to be able to conduct electricity.
