Radiation, conduction, and convection
You may want to look on this website!
Within the pot handle (solid) heat transfer is by conduction. Within a persons hand heat is transferred namely by conduction. Heat convection does occur by motion of the body fluids but it's slower. When you grab the hot handle of a pot you can immediately feel the sensation of "hot".Heat conduction is the mechanism responsible for this fast transfer.
Radiant heat (electromagnetic waves) does not require a medium. Sunlight, infrared light, microwaves are all radiant heat in the form of electromagnetic radiation.
The transfer of heat by fluid is convection.
No, in the universe radiation heat transfer is by far the largest transfer.
Yes, whereas convection heat transfer is the transfer of heat via a liquid, and radiative heat transfer occurs through empty space (like the heat you feel from the sun).
There is a special mechanism that controls heat transfer.
heat transfer through convection.

You have the mechanism of heat transfer correct but the name for it incorrect! The process where slow movements of mantle rocks transfer heat is known as convection.
The predominant heat transfer mechanism used to transfer heat from the pan to the stove burner is radiation.
i wanted to know the effect of the above question on vegetable
Why is conduction important?
A broad question, so I will give a broad answer. A driving force is needed and what drives heat transfer is simply temperature differences between two bodies. The mechanism at say a molecular level is really just the exchange of the energy from molecules to molecules. Higher energy molecules will collide with lower energy molecules and voila, you have heat transfer.
"Conduct" and "convection" are two different processes of heat transfer. When heat is transferred through a gas, the primary mechanism is convection.
