Question

In which of the following situations is heat transferred from the source to popcorn kernels by the method of conduction?

Answer 1

Answer:

Kernels are placed in a pan on a stove

Explanation:

Heat transfer by conduction involves the actual movement between particles of the medium. For conduction to occur, the particles must be in contact with the heating medium or the body at a higher temperatures.

For the popcorn kernels to conduct heat using the conduction heat transfer process, the kernels are placed in contact with the heat source using the frying pan. The stove is the heat source.

When put a knife in contact with fire, it is heat transfer by conduction.
