1. What is Critical Temperature of Wohl's Real Gas?

Definition: Critical Temperature is the highest temperature at which the gas can be liquefied by pressure alone.

Purpose: This calculator determines the critical temperature based on Wohl's equation of state parameters.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T'_c \) — Critical Temperature (Kelvin)
• \( P_c \) — Critical Pressure (Pascal)
• \( V'_c \) — Critical Molar Volume (m³/mol)
• \( [R] \) — Universal gas constant (8.314 J/mol·K)

Explanation: The formula relates critical temperature to other critical parameters in Wohl's model.

3. Importance of Critical Temperature

Details: Critical temperature is essential for understanding phase behavior and designing processes involving real gases.

4. Using the Calculator

Tips: Enter the critical pressure in Pascals and critical molar volume in m³/mol. Both values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What is Wohl's equation of state?
A: It's a cubic equation of state used to model real gas behavior, similar to van der Waals but with different parameters.

Q2: How accurate is this calculation?
A: It provides theoretical values based on Wohl's model; actual values may vary for specific gases.

Q3: What are typical critical temperature ranges?
A: Common gases range from 33K (hydrogen) to 647K (water), but this varies widely.

Q4: Can I use this for any gas?
A: Yes, but results are most accurate for gases that follow Wohl's equation of state behavior.

Q5: What if I only have critical temperature and need other parameters?
A: Use our other calculators to solve for different variables in Wohl's equations.
