Answer:
Liquid a has a lower boiling point than liquid b.
Step-by-step explanation:
Hello,
In this case, volatility is associated with three factors:
1. Vapor pressure: this is the pressure exerted by the gas molecules in equilibrium with the liquid. The higher the vapor pressure, the higher the volatility.
2. Intermolecular forces: are the interactions attracting or repelling the material's molecules. The stronger the forces, the lower the volatility as the molecules remain strongly closer.
3. Boiling point: is the condition of both temperature and pressure at which a liquid passes from liquid to gas. The lower the boiling point, the higher the volatility as more molecules easily pass from liquid to gas.
In such a way since liquid a is more volatile than liquid b, the answer is liquid a has a lower boiling point than liquid b based on the aforesaid factors.
Best regards.
