What does ‘Space Complexity’ mean ? What is the Principle of Moments? It has probably seen that if a cup of hot tea is left on a table for a convection oven sweet potato cubes period, it cools down.

This is due to heat loss to the environment. As a result, heat transfer is described as the transmission of heat or thermal energy from one physical system to another. Therefore, when two bodies have a temperature differential, heat is transported from the hot body to the cooler body. Conduction, convection, and radiation are the three most frequent ways of heat transfer.

The initial heat transmission between the item and the fluid occurs by conduction, but the bulk of the heat transfer occurs because of fluid motion. Solids do not experience convection because their basic particles do not move. The process of heat diffusion in solids is known as thermal conduction. Under normal conditions, gases and liquids are poor heat conductors, however, they may quickly transport heat by convection. Convection Heat Transfer: How Does It Work?
