← ScienceWhich outcome initiates cavitation when liquid temperature increases inside a closed hydraulic system?
A)Vapor pressure reaches fluid pressure✓
B)Viscosity surpasses material shear strength
C)Fluid density matches container density
D)Surface tension drops below critical point
💡 Explanation
Cavitation begins when increased liquid temperature raises vapor pressure; the *phase transition* from liquid to vapor occurs because of exceeding hydrostatic pressure; therefore vapor bubbles form, rather than liquid remaining stable, even though system volume is constant.
