Phase changes!a. Write out the Clapeyron equation and explain what it describes.b. Write out the Clausius-Clapeyron equation and explain what it describes.c. Calculate the boiling temperature of water at an elevation of 1700 m (approximately the height of Boulder, CO) where the atmospheric pressure is ~0.83 atm. You may use the fact that water boils at 373 K, 1 atm, and that the enthalpy of vaporization is 6.01 kJ/mol.
