← ScienceWhich outcome occurs when volatile liquid partially evaporates?
A)Remaining liquid cools via evaporative cooling.✓
B)Superheating dominates over liquid phase mixture
C)Overall kinetic energy remains constant.
D)Vapor pressure significantly decreases momentarily.
💡 Explanation
Evaporative cooling occurs because molecules with the highest kinetic energy escape as vapor during the phase change; therefore, the average kinetic energy and thus temperature of the remaining liquid is reduced, rather than superheating.
