Concept explainers
(a)
Interpretation:
The given statement “for systems in a state of physical equilibrium, no net macroscopic changes can be detected” is true or false has to be indicated.
Concept Introduction:
Physical equilibrium is a state in which two physical processes which are opposing to each other takes place at the same rate at this moment there is no net macroscopic changes can be happened but system is dynamic and at equal rate the forward and reverse process are occurred.
(b)
Interpretation:
The given statement “for a liquid-vapor equilibrium situation, the two opposite processes occurring are evaporation and condensation” is true or false has to be indicated.
Concept Introduction:
Physical equilibrium is a state in which two physical processes which are opposing to each other takes place at the same rate at this moment there is no net macroscopic changes can be happened but system is dynamic and at equal rate the forward and reverse process are occurred.
