Convection refers to the transfer of heat through the movement of a fluid, such as air or water. This occurs when the fluid particles near the heat source become heated and rise, displacing cooler particles which then get heated as well. As a result, a convection current is created, allowing heat to be transferred from the hotter region to the cooler region.
Conduction is the process of heat transfer through direct contact between two objects or substances. In this process, heat energy is transferred from a region of higher temperature to a region of lower temperature by the collision of particles within the objects or substances. The transfer continues until both objects reach thermal equilibrium, where they have the same temperature.
Radiation refers to the transfer of heat through electromagnetic waves. It does not require a material medium for heat transfer and can occur in a vacuum. Heat energy is emitted in the form of electromagnetic waves, such as infrared radiation, from a warmer object to a cooler object. These waves travel at the speed of light and can be absorbed, reflected, or transmitted by objects they encounter.
