Unformatted text preview: the mo lecules of the liquid are less attracted to each other in liquid phase (acetone, alcoho l), they escape easier into the vapor phase. Such liquids are called VOLATILE LIQUIDS NOTE: At the same temperature: pv(acetone) > pv(alcohol) > pv(water) most least volat ile volatile o t ( C) 3 Chemistry 101 Chapter 11 BOILING POINT Atmospheric Pressure NOTE:
· As the temperature increases, the vapor pressure (pv) increases.
Vapor Pressure · When: Patm = PV THE LIQUID BOILS water Experimental evidence o f bo iling:
· Bubbles of water vapor form WITHIN the liquid water · BOILING POINT is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure (Patm = PV) 4 Chemistry 101 Chapter 11 · Consider the fo llowing situat ions:
· At mospheric Pressure = 1.00 atm · At mospheric pressure = 0.83 atm (High alt itude) · Bo...
