← ScienceWhich pressure change results when water boils in reverse?
A)Pressure instantly becomes nearly zero
B)Pressure experiences little considerable change
C)Vapor pressure drastically decreases✓
D)Heat lowers pressure temporarily outward
💡 Explanation
A decrease in temperature will trigger condensation. This causes vapor pressure drastically decreases and the steam converts back to liquid water, because decreased molecular motion reduces escaping tendency; therefore overall pressure declines, rather than immediate or thermal based.
