conduction

Conduction is the transfer of heat through a material without the movement of the material itself.

It mainly occurs in solids where particles are closely packed.

In conduction, heat flows from a region of higher temperature to a region of lower temperature.

The particles in a solid vibrate and pass energy to neighboring particles.

Metals are good conductors of heat because they have free electrons.

Materials like wood and plastic are poor conductors and are called insulators.

Conduction does not involve any bulk movement of matter.

The rate of conduction depends on the type of material and temperature difference.

It is commonly seen in daily life, such as a spoon getting hot in a cup of tea.

Conduction is one of the three main modes of heat transfer, along with convection and radiation.
