Activity 8 The figure below shows the vapor pressures of ether, ethanol and water as a function of temperature. Use the figure to estimate the boiling points for these three liquids at sea level (at sea level, the atmospheric pressure is 1 atm or 760 mm Hg).. Recall that the definition of boiling point is the temperature when the vapor pressure above a liquid equals atmospheric pressure. Boiling point at sea level Ether Ethanol Water If the liquids were in a lab in Colorado, where the atmospheric pressure is lower (say, 600 mm Hg) how would their boiling points change? What would the BPs be at this altitude? Boiling point at high altitude (atmospheric pressure 600 mm Hg)Ether Ethanol Water What is the approximate vapor pressure of ethanol and of waterat 40C?
