← ScienceWhich consequence results when rapid sublimation occurs in spacecraft electronics?
A)Component overheating from increased resistance
B)Material embrittlement due to differential contraction
C)Dielectric failure due to outgassing products✓
D)Reduced thermal conductivity from phase changes
💡 Explanation
Outgassing worsens during sublimation, producing volatile organic compounds; therefore, dielectric failure in insulators occurs because released gases reduce the electrical breakdown voltage, rather than thermal or mechanical failures from expansion.
