← ScienceWhich outcome occurs when rapid volumetric expansion causes the vapor phase collapse during cavitation?
A)Acoustic energy induces material pitting✓
B)Increased surface tension stabilizes bubbles
C)Fluid density decrease damps oscillations
D)Thermal equilibrium prevents bubble collapse
💡 Explanation
When rapid expansion induces bubble collapse, intense acoustic energy focuses locally because implosion intensifies the pressure; this creates Acoustic cavitation. Therefore, pitting occurs, rather than stabilization or damping which demands energy dispersion.
