← ScienceWhich outcome occurs when rapid adiabatic expansion causes steam's phase transition, exiting a choked De Laval nozzle?
A)Increased liquid droplet formation✓
B)Superheated vapor phase stability
C)Uniform homogenous gas mixture
D)Reversible isentropic flow increase
💡 Explanation
Increased liquid droplet formation happens due to homogeneous nucleation because rapid expansion cools the saturated vapor below its saturation temperature, therefore causing spontaneous condensation rather than remaining vapor, due to lack of nucleation sites.
