Critical Molar Volume Formula:
From: | To: |
Definition: Critical Molar Volume is the volume occupied by gas at critical temperature and pressure per mole according to Wohl's model.
Purpose: This calculator helps determine the critical molar volume which is essential for understanding gas behavior under critical conditions.
The calculator uses the formula:
Where:
Explanation: The formula relates critical molar volume to the critical temperature and pressure of the gas.
Details: Critical parameters are essential for understanding phase behavior and designing processes involving real gases.
Tips: Enter the critical temperature in Kelvin and critical pressure in Pascals. Both values must be > 0.
Q1: What is the significance of critical molar volume?
A: It represents the volume occupied by one mole of gas at its critical point, important for phase behavior calculations.
Q2: How does this differ from ideal gas behavior?
A: Wohl's model accounts for real gas behavior at high pressures and near critical conditions.
Q3: What units should I use for input?
A: Temperature must be in Kelvin and pressure in Pascals for accurate results.
Q4: Can I use this for any gas?
A: Yes, as long as you have the correct critical temperature and pressure values for the specific gas.
Q5: Why is the universal gas constant used?
A: It's a fundamental constant that relates energy, temperature, and amount of substance in thermodynamic equations.
