Heat transfer is described in thermodynamic systems as the transport of heat beyond a system's border due to a temperature difference between the system and its surroundings.
Heat transfers from one location to another can take three different forms.
The process through which heat flows is determined by the nature of the medium, and the flow of heat is determined by the temperature of the regions.
The three categories are conduction, convection, and conclusion.
Conduction is the mechanism by which heat is transported from a warmer region of the body to a colder part of the body by transferring energy from one particle of an object to another without the particles moving from their equilibrium locations.
The transfer of heat from items with a higher temperature to those with a lower temperature.
The transfer of fluid molecules from high-temperature to low-temperature environments.
Convection is the process of heat transmission from one layer of a fluid to another layer through the displacement of the fluid's particles.
Convection is the method by which gases and liquids move heat.
For instance, in the winter, the atmosphere over the ocean is hotter than on land. As a result, air rushes from the land to the ocean in a north-easterly direction.
Radiation is the process of transferring heat from one location to another without the need for any heat-transfer medium.
The sun's heat, for example, is transmitted to the earth by radiation. Like light waves, they can reflect and refract.
Hence, in a liquid, heat is transferred mainly by conduction and convection.
