Why is a blanket a better conductor of heat when it's wet rather than it being dry?
the blanket has water and water is a very good conductor so a wet blanket is a better conductor than a dry blanket
Why is a rag a better conductor of heat when wet than when dry?
A dry rag has quite a bit of air trapped in its structure, and air is an insulator of heat. Replace the air with water, which conducts heat much better than air does, and the heat conductivity will be greatly increased.
Is aluminum foil a better heat conductor than metal?
no because aluminum foil is a metal
Is water a conductor of heat?
In real life, water is a poor heat conductor, compared with metals, but better than insulating solids, such as wood. Metals transfer heat through electron movement and phonons. Water transfers heat mainly through Brownian movement and convection. Insulating solids transfer heat through conduction (phonons mainly). Electron movement in metals is superior in speed than other mechanisms. The thermal conductivities [W·m−1·K−1] for silver, water, and oak wood are 429  , 0.58, and 0.17, respectively.

Is a iron nail a good heat conductor?
Yes. But, compared to what? Better than lead but not as good as silver.

Why is mercury a better conductor oh heat than water at room temperature?
huhuhu
Which is a better conductor of heat air or a copper wire?
A copper wire is a much better conductor of heat than air is.
Is cold water a better conductor than hot?
is cold water a better conductor than hot
Is water a better conductor than plastic?
No, water is not a better conductor of electricity than silver.Water can become a better conductor in acidic medium(by decreasing its pH). But it may split up into Hydrogen & Oxygen.
Does sylicon conduct heat?
Yes. Iron has better conductivity of heat and electricity than water and will heat up very fast. The same goes with carbon and silicon. If u get a chance to test them then u will know which is better conductor ( silicon should be better conductor since it is a metalloid)
Why are radiators metal?
Metals are a better heat conductor than plastics.
Why is a rag a better conductor of heat when wet than when dry?
A dry rag has quite a bit of air trapped in its structure, and air is an insulator of heat. Replace the air with water, which conducts heat much better than air does, and the heat conductivity will be greatly increased.
Is water or aluminum a better conductor?
Aluminum is a much better conductor than pure water. Salty water conducts as well as aluminum, however.
Why is metal a better conductor of heat than plastic?
Because wood contains water and volatile oils which conduct heat along internal pathways used by the tree to draw water from roots to leaves.
What is the best conductor of transferring energy as heat?
A metal. It's a better conductor than liquid, gas, or rubber.
Why does dry heat require higher temperatures for longer time periods to sterilize than does moist heat?
Water has a higher heat capacity than air. In other words, air is a very poor conductor of heat while water is a very efficient conductor of heat.
