Thermodynamic Equilibrium
Thermodynamic equilibrium refers to a state in which a system and its surroundings are in complete balance. This means that there is no net transfer of energy or matter between the system and its surroundings. In order for a system to be in thermodynamic equilibrium, three types of equilibria need to be satisfied: thermal equilibrium, chemical equilibrium, and mechanical equilibrium.
Thermal Equilibrium
Thermal equilibrium is achieved when the temperature throughout the system and its surroundings is uniform. This means that there are no temperature gradients or differences between different parts of the system. In thermal equilibrium, the system and its surroundings are at the same temperature and there is no heat transfer occurring between them.
Chemical Equilibrium
Chemical equilibrium is reached when the chemical reactions within the system and its surroundings have reached a state where the rates of the forward and backward reactions are equal. This means that there is no net change in the concentrations of the reactants and products. In chemical equilibrium, the system and its surroundings have the same chemical composition.
Mechanical Equilibrium
Mechanical equilibrium is achieved when there is no net force or torque acting on the system and its surroundings. This means that the system and its surroundings are not experiencing any acceleration or rotation. In mechanical equilibrium, the system and its surroundings are balanced and there is no net transfer of mechanical energy.
Thermal, Chemical, and Mechanical Equilibrium
For a system to be in thermodynamic equilibrium, it must satisfy all three types of equilibrium: thermal equilibrium, chemical equilibrium, and mechanical equilibrium. This ensures that there is no net transfer of energy or matter between the system and its surroundings.
Thermal equilibrium ensures that there is no net heat transfer, chemical equilibrium ensures that there is no net transfer of matter, and mechanical equilibrium ensures that there is no net transfer of mechanical energy. These three equilibria work together to create a state of complete balance between the system and its surroundings.
In conclusion, the correct answer is option 'D', which states that for a system to be in thermodynamic equilibrium, it must be in thermal, chemical, and mechanical equilibrium. These three types of equilibrium ensure that there is no net transfer of energy or matter between the system and its surroundings.
