Question

A system or a group of systems, in which there is no net macroscopic flow of energy or matter either within the system or in between systems is known as?

• A. Chemical equilibrium
• B. Thermal equilibrium
• C. Thermodynamic equilibrium
• D. Radiative equilibrium

Answer 1

The correct option is C Thermodynamic equilibrium

A group of systems can be said to be in thermodynamic equilibrium, when there is no net flow of matter or energy in any form between the systems. This means, that all the systems must have the same temperature, same pressure and same chemical potential or chemical composition.

Option C is the correct answer.
