← ScienceWhich outcome occurs when rapidly sublimating solid carbon dioxide cools electronics?
A)Material embrittlement from thermal contraction✓
B)Reduced circuit resistance due to phase transition
C)Increased dielectric strength in insulators
D)Enhanced signal transmission rates in conductors
💡 Explanation
Material embrittlement arises because rapid sublimation causes intense cooling and thermal contraction. This induces stress exceeding material limits rather than affecting resistance or signal in components; therefore, only embrittlement increases rather than dielectric or transmission phenomena.
