Advanced Knowledge of Conduction

Physics

definition

Conduction

Conduction is heat transfer between two bodies in contact and at different temperatures. It usually occurs between solids. Heat transfer by conduction is a slow process.

definition

Thermal conductivity

Thermal conductivity is defined as the rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance.()) and /() are some units of thermal conductivity.

example

application of thermal conductivity in daily life


Thermal conductivity is actually about the conduction of heat or transfer of heat.
Here are the some examples
1) A ice cube is melted in your hand because the heat from your hand transfer to the ice resulting in it's melting
2) Pouring of hot tea in a cup will make the cup of the also warm because of the heat transfer from tea to the cup.
3)Transfer of heat from iron to shirt while pressing is also a good example.
4) Transfer of heat during cooking to the food.
