← ScienceWhich outcome occurs when rapid decompression causes moist air cooling?
A)Water vapour undergoes adiabatic expansion✓
B)Nitrogen solubility increases rapidly
C)Internal energy increases slightly
D)Oxygen partial pressure sharply decreases
💡 Explanation
Adiabatic expansion of the air mass occurs due to a rapid decrease in external pressure, therefore the temperature drops causing the water vapour to transition to liquid via adiabatic cooling rather than another heat transfer mechanism, because there isn't enough time.
