Vapor Pressure Particles leave the bulk liquid and enter the vapor phase. Eventually, in a closed container, # of particles leaving = # entering liquid. This exerted pressure on the vessel is equal to the vapor pressure.

What factors affect vapor pressure? Intermolecular forces Substances experiencing more intermolecular forces will have lower vapor pressures. Temperature Increasing the temperature increases particle speeds, and increases vapor pressure.

Unformatted text preview: Heating Curve (draw in notes) For Water: Heat of fusion Hfus = 334 J/g Melt or freeze Heat of vaporization Hvap = 2261 J/g Evaporate or condense How much energy is required to convert 215 grams of water at 100C to steam at 100 C? Boiling What is boiling ? A liquid changing to a gas A liquid boils when its vapor pressure equals the external pressure on the liquid. Boiling Water Boiling on Earth Boiling Water Boiling on Earth Boiling in space (microgravity) How much energy is required to convert 121 g of ice at -5 C to water at 25C? Hfus = 334 J/g Hvap = 2261 J/g 4.184 J/(g-C) 1.84 J/(g-C) 2.09 J/(g-C) The blue values are specific heat Whats wrong with these aircraft? N-Wave Time (ms) Pressure 1 Atm...
