• Thermodynamic Triple Point of Pure Water:
• Equilibrium State:
• The unique thermodynamic state where solid ice, liquid water, and water vapor coexist in simultaneous thermodynamic equilibrium.
• Exact Physical Constants:
• Temperature: $0.01^\circ\text{C}$ ($273.16\text{ K}$ or $32.018^\circ\text{F}$).
• Pressure: $611.657\text{ Pascals}$ ($6.11657\text{ mbar}$ or $4.587\text{ mmHg}$).
• Fundamental baseline reference for lyophilization (freeze drying) cycles in food engineering.
• Conclusion: Temperature: 0.01°C; Pressure: 611.657 pascals (Option 1).

Correct option: (1) Temperature: 0.01°C; Pressure: 611.657 pascals
