← ScienceWhich outcome occurs when supercritical fluid enters a throttling valve?
A)Temperature change is neither heating✓
B)Isothermal phase equilibrium is maintained
C)Density remains constant throughout expansion
D)Full condensation back into its liquid
💡 Explanation
The Joule-Thomson Effect causes change, because rapid expansion forces energy reduction breaking intermolecular attractions; therefore the supercritical fluid changes temperature but it is a cooling process rather than a definite heating phase transition.
