Heat is transferred from one body to another. Heat transfer is a process is known as the exchange of heat from a high-temperature body to a low-temperature body. In convection, heat is transferred upwards.
Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. Convection is defined as the movement of fluid molecules from higher temperature regions to lower temperature regions. We observe the following things during the convention
- In convection, the heat transfer takes within the fluid.
- The heat transfer occurs due to the difference in density.
- The heat transfer occurs through intermediate objects. For example, heat transfer between air and water.
Examples of Convention
Listed below are examples of convention
- Boiling of water
- Circulation of blood in warm-blooded animals
