Question

A system in thermodynamic equilibrium will have the following equilibrium(s):-

• A. Thermal equilibrium
• B. Mechanical equilibrium
• C. Chemical equilibrium
• D. All of these

Answer 1

The correct option is D All of these

A system or a group of systems in thermodynamic equilibrium must be in thermal equilibrium, that is they both must have the same temperature. The systems must be in mechanical equilibrium, that is, they both must have the same pressure. The systems must also be in chemical equilibrium, that is their chemical composition and concentration must also be the same. Only in case of thermodynamic equilibrium, there will be no net flow of energy or matter from one system to the other.

Option D is the correct answer.
