Question

A solid transfers heat to another solid in contact with it by the process of ____________.

Answer 1

Explanation

1. Conduction is a process of heat transfer in solids only.
2. In solids, the molecules are packed closely together.
3. When one end of a solid is heated, the molecules absorb the heat energy and begin to vibrate rapidly.
4. These molecules, in turn, cause their neighboring molecules to vibrate.
5. This process continues along the iron rod and energy is transferred from the hot part to the cold part of the solid.

Hence, a solid transfers heat to another solid in contact with it by the process of conduction.
