Heat transfer is in three modes. Conduction, convection and radiation. In case of conduction, the speed of transfer depends on the conduction property of the material. In case of convection, the speed of transfer depends on the density of the liquid. In case of radiation, the speed of transfer of heat is at the speed of light in air medium and a little bit less in other denser medium.
Radiation .
Thermodynamics is the study of heat transfer. Heat moves from place to place from the release of heat (exothermic) and the absorptions of heat (endothermic).
Heat transfer rate in radiation is proportional to the fourth power of the temperature difference
Because transfer of heat requires particles, so solid objects will be better at conducting heat than gas.

It is heat transfer at speed higher than 0.3 Mach.
Wrong, transfer of heat by conduction does take place in fluids.
Radiation .
Conduction . . . depends on the properties of the material through which the heat is conductedConvection . . . depends on the physical movement of the material carrying the heat from level to levelRadiation . . . electromagnetic waves, moving from place to place at the speed of light.Looks like Radiation would transfer heat the fastest.
In all circumstances where a material is hotter than its surroundings, heat transfer takes place.

yes
It depends on the medium of heat transfer. For solids, it is conduction heat transfer. For liquids and gases, it is convection heat transfer. for vacuum (no medium), it is radiation heat transfer.
Heat transfer takes place due to collision in atoms (of which everything around us is mad). In solids these atoms are near to each other but in gas atoms are very very far from each other. So in case of solids, it is easier to transfer the heat in form of collisions but in air it is difficult to transfer these collisions. Note: Heat is transferred in form of collisions because heat increases speed of atoms. This speed when transferred to adjacent atoms by collisions, transfers the heat.
To speed up the transfer of heat energy.
