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 energy transfer from high temperature to low temperature. The cause of transfer is the temperature difference.
Simply put, a thermal difference is a difference in temperature between one object and another one, or one area of an object and another area of that same object.

The transfer of thermal energy when particles of a fluid move from one place to another is convection. Temperature is a measure of how hot or cold an object is compared to a reference point.Another AnswerNo. Heat (the term, 'thermal energy', is obsolete) is defined as 'energy in transit from a warmer body to a cooler body'. So a temperature difference is necessary for heat transfer to take place.It is not heat it is convection.

Heat transfer is the transition of thermal energy from a hotter mass to a cooler mass. When an object is at a different temperature than its surroundings or another object, transfer of thermal energy, also known as heat transfer, or heat exchange, occurs in such a way that the body and the surroundings reach thermal equilibrium; this means that they are at the same temperature. Heat transfer always occurs from a higher-temperature object to a cooler-temperature one as described by the second law of thermodynamics or the Clausius statement.
Temperature c;
That is called conduction.
Thermal Energy always transfer from the higher temperature to lower temperature until both bodies reach the same temperature or in thermal equilibrium with each other.
The heat transfer is possible by conduction, convection and radiation.
