Do kitchen pots made from different materials transfer heat at different rates?
Yes. But there are two different qualities of heat transfer. When you talk about the rate of heat transfer, you may be talking about the speed the pot changes temperature or how well it spreads heat. The rate of temperature change is called thermal diffusivity. A copper pot would change temperature about 1.3X faster than an aluminum pot, and 10X faster than an iron pot. How well it spreads the heat is called thermal conductivity. A copper pot would spread the heat about 2X better than an aluminum pot and about 8X better than an iron pot. This is assuming the thickness of each pot is the same. The ability of heat to pass through the pot, is also thermal conductivity. For some things you'd want a pot that transfers heat evenly and quickly, copper. For other things you'd want a pot that holds the heat, iron.
Is a copper pot a conductor of heat?
Yes
Why are pots made of iron?
SO they don't melt on the stove. Also they are durable, good conductors of heat. Copper pans are much more expensive, and so are cast iron ones.
Why is copper on the bottom of pots?
copper doesn't collect residue, and conducts heat into the inner pot very quickly
Think of a metal spoon in a pot of hot water. How do the particles of the water affect the particles of the spoon?
Conduction is what transfers the heat in this process. The fast moving particles in the hot electric coil collide with the slow-moving particles in the cool pot. The transfer of the heat causes the pot's particles to move faster. Then the pot's particles collide with the water's particles, which in turn collide with the particles of the spoon. As the particles move faster, the metal spoon becomes hotter.

Why is a cooking pot made out of copper cooks faster?
Copper is a conductor, which means it conducts heat more quickly, hence heating up faster. The same reason is for why copper is used in electricity cabling.
Why is iron pot found to hole after keeping a solution of copper sulphate in it for some days?
Iron is a more active metal than copper, so it replaces/displaces the copper in the copper sulfate, forming iron sulfate and copper. So the hole in the iron pot is where the iron atoms came from. This is called a single replacement/displacement reaction.

How much better is the thermal conductivity of a copper pot compared to a steel pot?
Copper is a much better conductor of heat than steel. This is why stainless steel cookware is clad in copper; it gets the heat in more effectively. Regarding a copper pot compared to a steel pot - I don't think anyone makes solid copper cookware. It leave a strange metallic taste in the mouth.
What is the thermal conductivity of a stainless pot compared to a copper-bottomed pot?
They're the same, actually. Copper-clad pots are always made out of stainless steel, so the pots are identical. The trick is that a copper-clad stainless pot absorbs heat better due to the copper cladding - the copper conducts heat better than stainless.
Why is copper on the bottom of pots?

Heat would best be transferred by conduction between?
A stove and a copper pot
What are the advantages or benefit of using copper bottom pots?
the basic idea behind the copper bottom pot is that it will supposedly heat more even across the surface of the bottom on the pot\pan
What type of metal pot is best for boiling water?
Copper transfers the greatest percentage of heat to the contents of the pot (water). As for the shape of the pot ..... lower and about 1" wider on all sides than the heat source.as wide as the heat source.
Why is copper used to make cooking pots and pans?
Because it is a great conductor. Gold and platinum are better but would make the pot too expensive. The bottom surface conducts the heat to evenly warm up the contents. The next best pot or pan for this is cast iron. Copper is a good conductor so the saucepan heats up better if it has a copper bottom.
