electric irons especialy the base which is the most important part of the iron is made up with composite iron and steel and some other metals with micro amounts which provides a iron better heat restorer and better for usage for long term use of it.
insulators although they take a long time to heat up, it takes a longer time to cool down. that's why if you heat water in a metallic container it takes more time for the water to cool down than the coontainer.
The amount of time it takes to cool down a house after turning air conditioning on would be dependent upon a number of factors. Some of those factors include the size of the home, insulation and outdoor temperature.

It takes approximately
bob is cool:)
I think that it takes about 1-2 minute to cool but I am not sure...
About 10 - 15 minutes.

<><><> I'm trying to find out the time it takes for a clothes iron to cool down after it was turned off, finished using it, to store it. <><><> If you want some general advice, maybe it is this: "Unplug it from the wall outlet and leave it for a full 24 hours before you put it away." Come on now, this question is like asking how long it takes a kettle or a saucepan to cool down from boiling water... There is no general answer. The time it takes to cool down enough to be put away depends entirely on 2 things: 1) the weight of the iron and 2) the temperature it is cooling down from. When it gets cool enough to be able to touch it safely without risking a burn to your finger, then if you leave it for one more hour it will be safe to put away. <><><>
It takes about half an hour.
Electric current in a coil can induce magnetism in an iron nail,place near the coil.when the electric current is cut off the magnetism in the iron nail disappears.the magnetism in the nail exist so long as there is electric current in the coil.this is an electromagnet.
It takes several hundred trillion years of a white dwarf to cool.
