This question is misguided. It is the energy type that is transferred, not the source. The type is heat.
conduction
it called heat transfer!
The energy transferred from a hotter object to a cooler one is referred to as heat. Heat flows from the object at a higher temperature to the object at a lower temperature until thermal equilibrium is reached.
The law says that energy can neither be created nor be destroyed. It can only be transferred from one form to another.... And energy always from higher potential to lower potential... Since hotter object is at high potential and cooler object at lower potential, the heat energy will flow from hotter to cooler object.
The energy transferred from a hotter object to a cooler one is referred to as heat transfer. Heat transfer occurs due to the temperature difference between the objects and always flows from higher temperature to lower temperature to reach thermal equilibrium.
The energy transferred from a hotter object to a cooler object is called heat transfer. Heat flows from the object with a higher temperature to the object with a lower temperature until thermal equilibrium is reached.
The air will cool down, while the other object gets hotter.
conduction
Heat is transferred through thermal conduction by direct contact between particles in a material. When there is a temperature difference between two objects in contact, the hotter object transfers heat energy to the cooler object through collisions between particles, causing the cooler object to heat up.
known as heat transfer, which occurs through three main mechanisms: conduction, convection, and radiation. In conduction, heat is transferred through direct contact between molecules. In convection, heat is transferred through the movement of a fluid. In radiation, heat is transferred through electromagnetic waves.
When one object is hotter than another, heat will be transferred from the hot object to the cold object. The hot object will cool down, and the cold object will heat up, until they are the same temperature.
This is the zeroth law of thermodynamics: objects at different temperatures will form a thermal equilibrium. The first law of thermodynamics says that energy can not be created or destroyed but can only change form. So the cooler object has to get hotter not the other way around.
