← ScienceWhich outcome occurs when hydrogen gas is rapidly decompressed?
A)The Joule-Thomson Effect causes cooling✓
B)Sonoluminescence produces ultraviolet emissions
C)A Fischer-Tropsch reaction generates alcohol
D)Hydrogen embrittlement weakens surrounding metal
💡 Explanation
Rapid decompression triggers the Joule-Thomson Effect, causing the gas to cool because energy is used to overcome intermolecular forces during expansion. Therefore, cooling occurs in hydrogen, rather than sonoluminescence or Fischer-Tropsch, that require different conditions.
