the densities of ice and water at 0 degrees Celsius
are 0.917g/cm3 and 1.000g/cm3 and those of water and water vapour
at 100 degrees celcius are o.958g/cms and 0.598g/cm3 respectively.
determine the difference between the chemical potentials of water
vapour and liquid water at 1.2 atm and woo degrees celcius.
calculate the difference in slope of the chemical potential against
pressure on either side of: normal freezing point of water and
normal boiling point of water

If we have water vapor at 100 oC and 1.2 atm we
should expect it to condense into liquid water as this is the most
stable phase under those conditions (i.e. the boiling point of
water should be higher than 100 oC at 1.2 atm ). This,
in turn, should mean that the chemical potential of the water vapor
should be larger than that of the liquid under those conditions.

A solution of ethylene glycol in water at 20 degrees celsius has a mass percent of 9.78% of ethylene glycol with a density of 1.0108 g/mL. The freezing point depression constant for water (solvent for all solutions) is Kf=-1.86 percent celsius kg/mol and the boiling point elevation constant is Kb=0.512 degrees celsius kg/mol. The density of neat water at 20.0 degrees celsius is 0.9982 g/mL. Answer the following: 1. What is the molarity of the solution? 2. What is the...
