Answer:
The correct answer is:
The natural tendency of systems is to evenly distribute energy until the objects are the same.
Explanation:
Thermal equilibrium
When ever two bodies differing in temperatures comes in contact with each other heat flow takes place from hotter body to cooler body in order to establish an equilibrium in which temperature of both the bodies becomes constant.
According to second law of thermodynamics:
When the energy of the system increases, matter moves more freely and change in entropy that is disorderliness of the system increases.
This increase in entropy is due to the energy possessed by the matter particles which has resulted in their motion or movement
With this increase in entropy of system, system will start interacting with its surroundings .And this interaction will results in evenly distribution of energy in its surroundings.
