Question

Definition of thermodynamic equilibrium in thermodynamics​

Answer 1

Here is your Answer:

Thermodynamic equilibrium is an axiomatic concept of thermodynamics. It is an internal state of a single thermodynamic system, or a relation between several thermodynamic systems connected by more or less permeable or impermeable walls. In thermodynamic equilibrium there are no net macroscopic flows of matter or of energy, either within a system or between systems.

In a system that is in its own state of internal thermodynamic equilibrium, no macroscopic change occurs.

Answer 2

IF ALL THE THERMODYNAMIC VARIABLE OF A SYSTEM REMAIN CONSTANT , WE SAY THAT THE SYSTEM IS IN THERMODYNAMIC EQUILIBRIUM WITH ITS SURROUNDING.
