← ScienceWhich outcome occurs when rapidly decreasing pressure on superheated water in a steam turbine?
A)Flash boiling induces rapid expansion✓
B)Steam temperature elevates by compression
C)Condensation minimizes pressure oscillations
D)Turbine blade corrosion prevents expansion
💡 Explanation
When pressure decreases rapidly, flash boiling occurs because the water, being above saturation temperature at the reduced pressure, rapidly undergoes a phase transition, forming steam and causing rapid expansion. Therefore, flash boiling induces rapid expansion, rather than temperature elevation, condensation, or prevented expansion, which require different thermodynamic processes.
