they transfer energy through sound water and air.
when two cold objects are rubbed against with each other...
heat transfer happens because objects that have energy, meaning vibrating atoms will bump against others and transfer the energy to the other atoms and so on. and also because things always have a tendency to have more entropy as time passes.
Conduction heat transfer refers to the process of heat transfer between two objects or regions in direct contact with each other. This transfer occurs due to the collision and transfer of energy between the molecules of the objects. It relies on the physical contact and proximity of the objects for heat to be conducted from the hotter object to the cooler one.
The transfer of thermal energy by molecules bumping into each other is known as conduction. Thermal energy is energy that comes from heat.

energy transfer occurs due to random collision of different molecules of the objects with each other,if the objects are of equal energy,there will be no detectable heat transfer,as molecules have same energy,but in between the objects having different heats the energy transfer occurs,due to the random collision of molecules with each other.

That sounds like a definition of "conduction" - as opposed to convection or radiation, which are other modes of heat transfer.
The type of heat transfer by direct contact is called conduction. Heat is transferred through a solid material or between two objects in direct contact with each other. This occurs as the particles in the material or objects collide and transfer energy to each other.

Heater is energy. Energy transfers from the higher energy unit to the lower energy unit, until they reach equilibrium. Equilibrium is when both objects contain the same amount of energy, therefore it is impossible for any to transfer between each other. The basic conditions for no heat transfer between two objects is for them to be the same temperature. To keep them at that same temperature, they would have to be floating in a perfect vacuum chamber so they had no contact with matter whatsoever. They would have to be shielded from infrared heat energy as well.

It's when the objects have a different temperature. As if one object were cold and the other was warm. -lu
