What occurs during thermal equilibrium?

During thermal equilibrium, two or more objects that are in thermal contact reach a state where there is no net exchange of heat between them. This means that the temperatures of the objects become equal, and as a result, thermal energy transfers from one object to another until they have the same temperature. Once this uniform temperature is achieved, heat flow stops, as there is no temperature difference to drive the heat transfer.

In this state, any fluctuations in energy transfer that might happen occur equally in both directions, effectively cancelling each other out. Thus, it is accurate to say that there is no significant exchange of heat between objects in thermal equilibrium, as their temperatures have equalized and no further heat flow is needed.
