Cooking with Conduction
Conduction - According to the American Heritage Dictionary, "conduction is the transmission through a medium or passage, esp. the transmission of electric charge or heat."
An example of conduction used for cooking is a stove.
- A stove generates heat, but it was originally designed specifically to cook food.
-
A stove consists of heating units called elements.
- According to the Yummy Physics website, "elements are composed of flat, coiled metal tubes that are made of nichrome - alloy resistance wires sealed inside stainless steel sheaths.
-
When a coil turns red ( as seen in the picture below), it shows that an electric current has passed through the wires and has generated heat that radiates out of the element.

- Glasstop and ceramic stoves heat in the same fassion except the elements are covered by glass or ceramic serfaces.
