Thermal energy is a transfer of kinetic energy from the movement of particles in a substance to another substance or area at a different temperature. This transfer causes the receiving substance to heat up and increase in temperature.
Thermal energy transfer occurs through conduction (direct contact), convection (movement of fluids or gases), and radiation (electromagnetic waves). Heat flows from areas of higher temperature to lower temperature until equilibrium is reached.
An object gains heat when energy is transferred to it from a higher temperature source. This transfer of energy causes the particles within the object to move faster, increasing its temperature.
The air temperature decreases as energy is transferred to the cooler object. This transfer of energy causes the air molecules to lose kinetic energy and slow down, resulting in a decrease in temperature.
I'm pretty sure it's thermal energy. I hope this isn't for science homework.... Love, Katie :)

The physical process that causes cooling and energy transfer is typically heat transfer, either through conduction, convection, or radiation. When objects of different temperatures come into contact, heat flows from the warmer object to the cooler one until thermal equilibrium is reached. This process occurs until the objects reach the same temperature, allowing for energy transfer to balance out.
An energy transfer does not always result in a phase change because the energy can be used to increase the temperature of a substance without causing it to change from one phase to another. Phase changes occur when a substance reaches a specific temperature and energy level that causes its molecular structure to rearrange, such as melting or boiling.
It's when the objects have a different temperature. As if one object were cold and the other was warm. -lu
In thermodynamics, work refers to the energy transferred when a force acts on an object and causes it to move. Heat, on the other hand, is the energy transferred between objects due to a temperature difference. Work involves mechanical energy transfer through motion, while heat involves thermal energy transfer through temperature differences.
