• 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

• Classification of Expansion Devices in Refrigeration Systems:
• Regulate refrigerant mass flow and reduce pressure from condenser to evaporator:
• (I) Capillary tube: Constant-bore restrictor used in domestic refrigerators.
• (II) Thermostatic Expansion Valve (TEV/TXV): Modulating valve maintaining constant evaporator superheat.
• (III) High-side float valve: Liquid-level float valve discharging condensed liquid to flooded evaporators.
• All three are standard refrigeration expansion devices.
• Conclusion: (I), (II) and (III) (Option 2).

Correct option: (2) (I), () and (Ill)
