1. What is Condensation Point?

The condensation point is the temperature at which a vapor begins to condense into a liquid. It occurs when the vapor pressure equals the saturation pressure of the substance at that temperature.

2. How Does the Calculator Work?

The calculator uses the condensation point principle:

Where:

• \( T_{cond} \) — Condensation temperature (°C)
• \( P_v \) — Vapor pressure (Pa)
• \( P_{sat} \) — Saturation pressure (Pa)

Explanation: Condensation occurs when the vapor pressure of a substance equals its saturation pressure at a given temperature, causing the vapor to transform into liquid.

3. Importance of Condensation Point Calculation

Details: Accurate condensation point calculation is crucial for HVAC systems, refrigeration, chemical processes, atmospheric science, and industrial applications where phase changes are important.

4. Using the Calculator

Tips: Enter vapor pressure and saturation pressure in Pascals (Pa). The calculator determines if condensation is occurring based on the relationship between these pressures.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between vapor pressure and saturation pressure?
A: Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid, while saturation pressure is the maximum vapor pressure at a given temperature before condensation occurs.

Q2: How does temperature affect condensation point?
A: Higher temperatures generally require higher pressures for condensation to occur. The relationship is described by the Clausius-Clapeyron equation.

Q3: What factors influence condensation point?
A: Temperature, pressure, humidity, and the specific properties of the substance all influence the condensation point.

Q4: Why is condensation important in real-world applications?
A: Condensation is essential in distillation, power generation, refrigeration, weather forecasting, and many industrial processes.

Q5: Can this calculator be used for all substances?
A: The principle applies to all substances, but specific saturation pressure values depend on the substance's properties and temperature.
