← ScienceWhich outcome occurs when an adiabatic valve releases compressed refrigerant?
A)Temperature equilibrates via Joule-Thomson effect✓
B)Kinetic energy increases without influence
C)Enthalpy increases despite no work
D)Work is done to create temperature
💡 Explanation
Because valves introduce a pressure drop into the refrigerant stream, the Joule-Thomson effect causes a temperature change that equilibrates gas temperature; Therefore temperature change occurs rather than kinetic increase as that would require work.
