← ScienceWhich outcome occurs inside a heat engine when a liquid undergoes rapid adiabatic expansion to a vapor phase?
A)Temperature decrease drives further expansion✓
B)Entropy remains constant during evaporation
C)Thermal conductivity increases linearly
D)Cavitation causes localized superheating
💡 Explanation
When a liquid expands adiabatically into a vapor phase, the expansion causes its temperature to decrease due to the work done against external pressure, according to thermodynamic principles. Therefore temperature decrease drives further expansion, rather than constant entropy, increased conductivity, or localized superheating which require different conditions.
