in thermal contact with each other
The transfer of energy between two objects at different average thermal kinetic energies (temperatures) is referred to as heat transfer. It is always called heat transfer, regardless of what kind of energy is being transferred.
heat
If the two objects are in a vacuum and there is nothing between them, heat transfers by radiation.If they are separated and their is air between them, heat transfers by convection.If the two objects are in contact (touching) with each other, heat transfers by conduction.
Heat is not the transfer of thermal energy. Heat is the thermal energy. What drives itacross a boundary between substances or objects is a difference in their temperatures.
Thermal insulation is the reduction of heat transfer (the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.

in thermal contact with each other
Energy is mainly transferred in the form of heat. So,transfer of heat energy from one body to another by direct contact is called thermal conduction.
