Question

What is Thermodynamic equilibrium?​

Answer 1

Answer:

Two physical systems are in thermal equilibrium if there is no net flow of thermal energy between them when they are connected by a path permeable to heat. ... A system is said to be in thermal equilibrium with itself if the temperature within the system is spatially uniform and temporally constant.

Step-by-step explanation:

Answer 2

Answer:

Thermodynamic equilibrium is an axiomatic concept of thermodynamics. ... 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.
