← ScienceWhich risk elevates when ice blockage prevents phase switching fluid flow?
A)Coolant pressure rapidly exceeds chamber ratings✓
B)System thermal efficiency increases steadily
C)Heat generation precisely equals load capacity
D)Coefficient of transfer remains unaffected
💡 Explanation
Overpressure risk skyrockets because blocked flow prevents phase transition cooling via evaporation. The increased volumetric heat generation drives pressure upwards rapidly, therefore exceeding system's rated capacity under constrained flow, rather than achieving thermal equilibrium or transfer efficiency unaltered.
