← ScienceWhich outcome results from decreased pressure during liquid-gas phase transition?
A)Reduced boiling point temperature✓
B)Increased latent heat absorption
C)Elevated enthalpy of vaporization
D)Shifted equilibrium vapor pressure
💡 Explanation
Reduced pressure lowers the kinetic energy required for molecules to overcome intermolecular forces; therefore, the boiling point temperature declines, because boiling occurs sooner, rather than a higher boiling point under increased pressure, where more energy would be needed.
