Please explain why these answers are correct. What interpretation should be made? please also explain what relative humidity has to do with the chemical potential

7. What is the relationship between the chemical potential of liquid water () and water vapour (B)(,=), and the vapour pressure of water in each of the following situations? Atmospheric pressure is 1 bar in all cases. a) Boiling water. b) 50% relative humidity at 25C c) 100% relative humidity at 25C Note: 100% relative humidity means that the air is saturated with water, so it's at the dew point. ps: 100%RH means that we reached the dew point, or first droplet of water, so we are at phase quilibrium. The partial pressure of water at this point is the saturation vapour pressure of water nat you would calculate with Antoinne. 7.: a) ==;PVAP (water) = 1 bar b) >p;PVAP( water )=1.60kPa c) 1=g;PVAP (water )=3.19kPa
