conduction
In conduction, heat transfer occurs through the collision and transfer of kinetic energy between particles in a material. When a hotter particle collides with a cooler particle, it transfers some of its kinetic energy, causing the cooler particle to increase in temperature. This process continues through the material, resulting in the transfer of heat energy from a region of higher temperature to a region of lower temperature.
The process of energy transfer that does not occur due to a temperature difference is called radiation. Radiation is the transfer of energy through electromagnetic waves, such as light or microwaves, without the need for a difference in temperature between the objects involved.
heat is the transfer of thermal energy because of difference in what?
As particles move faster, they have higher kinetic energy, which translates to higher temperature. When particles collide and transfer energy, it can raise the overall temperature of the system. This motion and energy transfer are fundamental to understanding how temperature changes in a system.
If the temperature difference between an object and its surroundings is reduced, the rate of energy transfer between them will also decrease. This is because the driving force for heat transfer is smaller when the temperature difference is smaller.

heat is the transfer of thermal energy because of difference in what?
This is due to statistics. It is quite possible for a low-energy particle (atom or molecule) to transfer energy to a high-energy particle, but on average, more energy will be transferred the other way.
As particles move faster, they have higher kinetic energy, which translates to higher temperature. When particles collide and transfer energy, it can raise the overall temperature of the system. This motion and energy transfer are fundamental to understanding how temperature changes in a system.

conduction, convection or radiation
The temperature of the two objects must be the same in order to stop the transfer of energy between them. Energy will transfer as long as there is a temperature difference between the objects.
The flow of energy due to a temperature difference is called heat transfer. Heat transfer can occur through three main mechanisms: conduction, convection, and radiation.
Conduction
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.
