Wood conducts heat very poorly - it has a very low conductivity-so would it still have a low conductivity if it was hot?

It really depends on how dense the wood is and how direct the heat is applied to the wood. Wood will coduct some heat even dry but not much. However it will burn... so if you heated the wood to the point of nearly burning with a lot of heat, it would possibly burn your hand. It has to be constant and can happen rarely that's why pan handles are rarely made of wood. If placed in a hot oven for long enough you will get burned just the same but it will take a lot more time
Iron conducts heat very well though mostly because it holds heat. This is possible because of a latticelike network of molecules. Metallurgy is fascinating and you should study and read up on it

Why is the conductivity of purified water not zero?
conductivity is not zero because water itself has ions i.e. H+ & OH- so conductivity cannot be zero. even if you use EDI still some conductivity will be left it will be almost negligible but still conductivity will be there.
If wood has very low conductivity does it still have low conductivity if it is very hot?
Yes, increasing the temperature of an insulator is not likely to make it more electrically conductive. Resistance generally increases as temperature increases. Some materials conduct electricity better when they are very cold, however.
How you can measure the electric conductivity of solid liquid mixture?
The long and short of measuring the electrical conductivity of elements involves little more than making a short piece of "wire" out of a given (pure) element and then applying a voltage and measuring the current. Take into account the external resistance, and the length, cross sectional area and temperature of the element and make some calculations. It's a little more involved with liquids, and tougher still with gaseous elements, but a conductor will "conduct" based on its composition, length, cross sectional area and temperature.
What metal has a low thermal conductivity?
The metals which are less reactive and not very shiny are generally less conductive than others.These metals generally have low melting and boiling points. The above result has been proven but still it is not true for all the metals,i.e,there are certain exceptions.Eg)mercury is good conductor of heat but not that good conductor of electricity.But there is no need to remember the conductivity of different metals,you just need to know some of the best conductors and some of the worst ,that's all.
How long does it takes for coal to form?
Most coal comes from the Carboniferous period, which ended 290 million years ago. Low grade lignite coals can form in a few thousand years or sometimes less, but they still contain some water and burn very poorly.
How do you use thermal conductivity in a sentence?
Thermal conductivity involves the movement of energy while the as a whole is still. Gases are said to have low thermal conductivity, as they transfer heat poorly. Metals have much better thermal conductivity, as they will heat up and cool down relatively quickly.

Does ozone increase water conductivity?
Yes, it does. I am still waiting for some good reasons. ^^
How should you treat your ex-girlfriend when you went out for a day but you still have feeing for her?
Poorly.
Does a karate master still teach classes?
No, a master still teaches. The 10th degree grand master in my style still conducts classes daily. and he's 80 years old.
Why is gold still used in the industrial processes?
It is still extensively used in electrical connectors in the electronics industry. Its conductivity is less than that of copper but it is used for its resistance to corrosion.

Why does my 1995 Dodge Intrepid still bring up a map sensor code when i have replaced it and the car still runs poorly?
You need to test the wires at the map.
How was women's suffrage treated in the West?
it was treated poorly because they still didn't believe women should have their own rights.
What happens when the human eye stops working?
Depends if it is one of the eyes you may still look out of the other one but poorly.
Are poor conductor nonmetals at room temperature?
Poorly conducting nonmetals can be at a wide range of temperatures and still conduct poorly. Glass, for example, is a poor electrical conductor whether at room temperature, or very hot, or very cold.
