The village shaman is up to no good again. Having calibrated their pulley system, they now have a constant source of perfect liquid (cp,l = 5R) potion at T = 20.0°C. They would now like disperse the potion amongst the villagers for some likely nefarious purpose... They decide to convert it to a vapor (Cp,v 15R) and let it then become an aerosol, which the villagers will inhale unsuspect- ingly. The potion is known to vaporize at 70°C with an enthalpy of vaporization Ahvap = 25 kJ/mol. =
