Here's why:
* Heat Transfer: Heat always flows from a hotter object to a colder object. When two objects are in contact, heat energy will transfer from the warmer object to the cooler object until their temperatures equalize.
* Equilibrium: Thermal equilibrium is the state where there is no net heat transfer between the objects. The objects have reached a stable temperature, and there is no longer a temperature difference driving heat flow.
It's important to note: Even though the objects have reached the same temperature, they may not have the same amount of heat energy. This depends on their specific heat capacity and mass.
