Does glass have a higher thermal conductivity than wood?
Depending on the glass, it has a K value between 0.8 and 1.1 Wood has a K value of between 0.04 and 0.4 The higher the K value the better the thermal conductivity. Thus glass has a higher thermal conductivity than wood.
Does a cotton has higher thermal conductivity than silk?
yes
Do nonmetals or metals have high thermal and electrical conductivity?
Both thermal conductivity and electrical conductivity tend to be higher in metals than in most other materials.
What has the highest thermal conductivity?
Diamond is the best thermal conductor around room temperature. Diamond has a thermal conductivity of more than 2,000 watts per meter per Kelvin, which is five times higher than the best metals such as copper.
What metal conducts heat faster stainless steel or aluminum?
Aluminum. It has a higher value for thermal conductivity than stainless steels.

Why do you fell hotter on a humid day?
it has something to do with physics: every "material" has its own thermal conductivity. that means the energy transferred increases as the thermal conductivity of the material increases. thats why if you tough a piece of wood which has the exact same temperature of a piece of metal it still will feel less warm. because wood's thermal conductivity is lower than metals, it will "transfer" less energy (energy = temperature) per second to your finger, so you will feel it less. so figure thermal conductivity of humid air is higher than dry air.
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.
How can I see the difference between gold and copper?
Copper and gold are different metal elements with different properties. The thermal conductivity of gold is 318W/mK, whereas the thermal conductivity of copper is slightly higher at 401W/mK. The electrical conductivity of copper is slightly higher at 5.96 x107 S/m than gold which is 4.11×107 S/m.
Why is is more difficult to weld aluminum than mild steel?
aluminum has a lower melting point, higher thermal conductivity, and doesn't change color before it goes molten
What is conductivity bridge?
The thermal conductivity detector (TCD) is a bulk property detector and a chemical specific detector commonly used in gas-liquid chromatography. [1]This detector senses The thermal conductivity detector (TCD) is a bulk property detector and a chemical specific detector commonly used in gas-liquid chromatography. [1]This detector senses changes in the thermal conductivity of the column effluent and compares it to a reference flow of carrier gas. Since most compounds have a thermal conductivity much less than that of the common carrier gases of helium or hydrogen, when an analyte elutes from the column, the effluent thermal conductivity is reduced and produces a detectable signal. changes in the thermal conductivity of the column effluent and compares it to a reference flow of carrier gas.

If a hot piece of thick glass is clipped in cold waterit breaks.Give reason?
The edges of the thick glass will cool faster than the center portion since the glass has low thermal conductivity. This produces a thermal gradient in the glass putting the outside edges in a state of tension stress. Glass fails in tension at a low value if any flaw exists on the edge surface.
