Critical Temperature Formula:
From: | To: |
Definition: Critical Temperature For Clausius Model is the highest temperature at which the substance can exist as a liquid. At this phase boundaries vanish, the substance can exist both as a liquid and vapor.
Purpose: This calculator determines the critical temperature based on the Clausius parameter a and pressure conditions.
The calculator uses the formula:
Where:
Explanation: The formula calculates the critical temperature by combining the Clausius parameter with pressure conditions and fundamental constants.
Details: Knowing the critical temperature is essential for understanding phase behavior, designing chemical processes, and predicting thermodynamic properties of substances.
Tips: Enter the Clausius parameter a, actual pressure in Pascals, and reduced pressure (dimensionless). All values must be > 0.
Q1: What is the Clausius parameter a?
A: It's an empirical parameter characteristic to equation obtained from Clausius model of real gas.
Q2: What is reduced pressure?
A: Reduced pressure is the ratio of the actual pressure of the fluid to its critical pressure (dimensionless).
Q3: Why is the universal gas constant used?
A: The gas constant provides the necessary thermodynamic scaling for the equation.
Q4: What units does this calculator use?
A: Pressure must be in Pascals, temperature results are in Kelvin.
Q5: How accurate is this calculation?
A: Accuracy depends on the validity of the Clausius model for your specific substance.
