Heat transfer is the transition of thermal energy from a heated item to a cooler item.
Heat transfer is the transition of thermal energy from a heated item to a cooler item.
That would be a description of heat transfer by conduction.
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
That sounds like a description of heat conduction.

Convection heat transfer is the transfer of heat by the movement of a fluid.
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
Radiation is the thermal energy transfer mechanism that does not require matter. It occurs through electromagnetic waves traveling through a vacuum or transparent medium, such as heat from the sun reaching the Earth.
The convective heat transfer coefficient of water is a measure of how easily heat can move through water. A higher convective heat transfer coefficient means heat can transfer more quickly. In a system, a higher convective heat transfer coefficient can increase the rate of heat transfer, making the system more efficient at exchanging heat.
They're both modes of heat transfer via material media.
convection
There is a special mechanism that controls heat transfer.
