-## Quick Example
-
-Compute the vapor pressure of water at 100 °C using the Antoine equation:
-
-```python
-from pathsim_chem.thermodynamics import Antoine
-
-# Antoine coefficients for water (NIST)
-antoine = Antoine(a0=23.2256, a1=3835.18, a2=-45.343)
-
-# Evaluate at 373.15 K
-antoine.inputs[0] = 373.15
-antoine.update(None)
-P_sat = antoine.outputs[0]  # ≈ 101325 Pa
-```
-
-Use activity coefficients in a simulation:
-
-```python
-from pathsim_chem.thermodynamics import NRTL
-
-# Ethanol-water NRTL model
-nrtl = NRTL(
-    x=[0.4, 0.6],
-    a=[[0, -0.801], [3.458, 0]],
-    c=[[0, 0.3], [0.3, 0]],
-)
-
-# Evaluate at 350 K
-nrtl.inputs[0] = 350
-nrtl.update(None)
-gamma_ethanol = nrtl.outputs[0]
-gamma_water = nrtl.outputs[1]
-```
