The transfer by collisions of atoms is called conduction. Transfer directly through space is radiationl
In order for heat to be conducted, there have to be collisions between atoms or molecules, in which energy is transferred from a faster moving particle to a slower moving particle. In a vacuum there are no particles, hence, no particle collisions and no heat conduction.
their kinetic energy is transferred to the electrons of the neighboring atoms and kinetic energy is conserved as most molecular collisions are elastic.
Atoms when Gamma rays go through them lose electrons, and Gamma rays also break bonds between atoms, these changes can damage matter.
Sound requires matter as sound is the vibration of matter. Light is more complex as it is the giving off of photons from atoms.
The current through a resistor or for that matter any conducting medium is caused by flow of electrons. These electrons do not flow like a stream through the resistor or conductor but undergo repeated collisions with the vibrating atoms of the resistor, transferring their kinetic energy to them. This in turn increases the vibrational energy of the atoms and manifest itself as heat in the resistor/ conductor. In turn this results in reduced drift velocity of the electrons resulting in reducing the current , thus acting as a Resistor.
Since that's what heat is (the motion of atoms), how better to transfer than by random collisions? yes.
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.

The current is the flow of electrons. Temperature is the movement of atoms. As the current increases there is more collisions between the atoms and the electrons. Some of the energy from the electrons is transferred to the atoms, thus they move faster and so the temperature increases.
By exciting the atoms in the matter. Pr. definition, heat is the jiggling of atoms, the radiant energy is shaking the atoms, by doing this the heat is transferred and absorbed.
Beaming matter through space and reconstructing the atoms.
Electrons are transferred from sodium atoms to chlorine atoms.

electrons are transferred to the atom from other atoms through direct contact
A covalent bond is formed when electrons are transferred from atom to atom.
