Temperature Formula:
From: | To: |
Definition: This calculator determines the actual temperature of a real gas using the Clausius parameter a, critical pressure, and reduced temperature.
Purpose: It helps in thermodynamics calculations for real gases where ideal gas assumptions don't apply.
The calculator uses the formula:
Where:
Explanation: The formula accounts for deviations from ideal gas behavior using the Clausius parameter and critical properties.
Details: Accurate temperature calculation is crucial for understanding gas behavior under various pressures, especially near critical points.
Tips: Enter the Clausius parameter a, critical pressure in Pascals, and reduced temperature (dimensionless). All values must be > 0.
Q1: What is Clausius parameter a?
A: It's an empirical parameter characteristic to the Clausius equation of state for real gases.
Q2: How do I find critical pressure?
A: Critical pressure is a property of each substance, available in thermodynamic tables.
Q3: What is reduced temperature?
A: It's the ratio of actual temperature to critical temperature (T/Tc), making it dimensionless.
Q4: Why use this instead of ideal gas law?
A: For real gases under high pressure or near critical points, ideal gas assumptions fail.
Q5: What are typical values for Clausius parameter a?
A: Values vary by substance, typically ranging from 0.01 to 10 Pa·m⁶/mol².
