← ScienceWhich outcome occurs when humidity reaches 100% during adiabatic expansion in an industrial cloud chamber?
A)Water vapor exhibits phase transition✓
B)Chamber temperature remains constant
C)Air pressure begins elevating linearly
D)Latent heat increases instantaneously
💡 Explanation
When humidity reaches 100% during adiabatic expansion, supersaturation occurs, leading to the phase transition of water vapor to liquid droplets through condensation, due to reduced temperature. Therefore, a phase transition results, rather than constant temperature, increased linear air pressure, or latent heat increasing which require external energy input.
