Chapter 12, Problem 12.139(choose chapter or problem)
At a picnic, a glass contains 0.300 kg of tea at 30.0 C, which is the air temperature. To make iced tea, someone adds 0.0670 kg of ice at 0.0 C and stirs the mixture. When all the ice melts and the final temperature is reached, the glass begins to fog up, because water vapor condenses on the outer glass surface. Using the vapor pressure curve for water that accompanies 75, ignoring the specific heat capacity of the glass, and treating the tea as if it were water, estimate the relative humidity.
