Practice question · Select all that apply
Which conditions must all hold for full thermodynamic equilibrium?
Hints
- Equilibrium has thermal, mechanical and chemical parts.
- Internal energy has no zero point and is irrelevant to equilibrium.
Show the answer
- A. Uniform temperature throughout
- C. Uniform chemical potential throughout
- D. Uniform pressure throughout
Why
Thermal, mechanical and chemical equilibrium must hold together. Internal energy has no absolute zero and plays no part in the definition, a system can be in perfect equilibrium at any energy.
