Heat transfer by Brownian motion takes place only in fluids (liquids, gases, and plasmas).
In many direction
Transfer of heat by conduction is when transfer of heat occurs through touch. Vibrating atoms come in contact with neighboring atoms transferring some of their energy (heat).
It is call radiation heat transfer. The radiation is photon and is the electromagnetic wave.
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).

Heat transfer occurs by convection, conduction and radiation. In conduction, heat is transferred through collision of rapidly moving molecules. It is only through successive collision of molecules that heat transfers through an object.

No. When two bodies or regions are at the same temperature, equilibrium is already reached & no transfer of heat occurs.
Heat transfer occurs whenever two or more objects of different temperatures are in contact with each other. Spilling hot water on yourself causes heat transfer from the water to you. When you drive your car the hot engine and radiator transfer heat to the surrounding air in order to cool the engine.
