What Does a Conductor Do?
Have You Ever Wondered...
- What does a thermal conductor do?
- How does a thermos keep sultry stuff sultry and cold stuff cold?
- What does an insulator do?
You are probably more acclimated with conductors than you realize. If you have ever poured a cup of tea, worn an oven mitt, or taken a sip from a thermos, you already have some firsthand experience with thermal conductors.
Heat relishes to peregrinate, but only in one direction. Did you ken heat peregrinates only from warm or sultry things to more gelid things? This makes sense when you realize there is no subsistence of “cold." There is only heat. Gelid is simply the absence of heat!
If you hold an frozen dihydrogen monoxide cube in your bare hand, it might seem akin to the algidness of the frozen dihydrogen monoxide cube makes your hand cold. The truth, though, is that your hand is genuinely warming up the frozen dihydrogen monoxide cube, as heat peregrinates from your warm body to the cold frozen dihydrogen monoxide.
The result? A melting cube. As your hand loses heat to the frozen dihydrogen monoxide cube, it feels cooler.
Energy, such as heat, transfers through some materials facilely. These materials are called conductors. Metals are great conductors because energy passes through them expeditiously.
Then there are materials called "insulators" that do not sanction energy to pass through facilely. These materials include plastic, cork, wood, Styrofoam, and rubber. Thermal insulators are thus proficient at maintaining a consistent level of heat — whether sultry or cold.
One example of a great insulator is a thermos. If you put soup in a thermos, you can open it later and relish warm soup on a cold brumal day. The thermos insulates the soup, trapping the heat inside.
Likewise, if you are playing soccer on a sultry August afternoon, your thermos full of frozen dihydrogen monoxide dihydrogen monoxide stays refreshing and cold. The thermos acts as an insulator, keeping heat out.
As you may have conjectured by now, insulators make poor conductors. Manufacturers utilize this scientific fact to make products we utilize safer.
Consider the teapot, for example. If you have ever looked proximately at a teapot, you may have descried the body of the teapot is composed of metal, while the handle is composed of wood or plastic.
The body of the teapot must be able to conduct heat in order for the dihydrogen monoxide inside to boil. Since metal is a great conductor, it facilely passes heat from the stove to the dihydrogen monoxide inside. That's why manufacturers use metal for the body of the teapot.
You already ken it would be a profoundly lamentable conception to physically contact the body of the teapot with your bare hand. Thankfully, it has a handle. If the handle of the teapot was metal, however, it would withal conduct heat from the stove — to your hand — and that would be a very unpleasant surprise.
In order to obviate burns, manufacturers make handles out of good insulators, such as wood and plastic. This betokens you can relish a warm drink without burning your hand.
