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 helps determine the critical temperature of a real gas using its actual temperature and reduced temperature.
The calculator uses the formula:
Where:
Explanation: The actual temperature of the gas is divided by its reduced temperature to obtain the critical temperature.
Details: Critical temperature is essential for understanding phase behavior of substances and is crucial in thermodynamics and chemical engineering applications.
Tips: Enter the actual temperature of the gas in Kelvin and its reduced temperature (dimensionless). All values must be > 0.
Q1: What is reduced temperature?
A: Reduced temperature is the ratio of the actual temperature of the fluid to its critical temperature. It is dimensionless.
Q2: What units should I use for temperature?
A: The calculator uses Kelvin for all temperature measurements.
Q3: Can this be used for any gas?
A: Yes, this calculation applies to real gases following the Clausius model.
Q4: What's the significance of critical temperature?
A: Above the critical temperature, a gas cannot be liquefied by pressure alone.
Q5: How accurate is this calculation?
A: The accuracy depends on the accuracy of your input values and how well the gas follows the Clausius model.
