Explain the the following Conduction, convection, and radius of heat

Conduction
Conduction is the transfer of thermal energy through direct contact between particles, without any bulk movement of the material itself. It primarily occurs in solids where vibrating atoms or molecules transfer energy to adjacent particles through collisions. For example, a metal spoon placed in hot coffee heats up through conduction.

Convection
Convection is the transfer of thermal energy through the movement of fluids (liquids or gases). This occurs when warmer, less dense fluid rises, and cooler, denser fluid sinks, creating a convection current that circulates heat. An example is boiling water, where hot water rises and cooler water descends.

Radius of heat
"Radius of heat" is not a standard scientific term in physics. It might be interpreted as the range or area over which heat is effectively transferred from a source, or the radius of influence of a heat source's thermal energy.
