On a particularly cold day, you are sitting inside your warm room, looking out a window. You are not sure how cold it is outside, but the inside of the window pane is 7.3 °C. Farther away from the window, the rest of the room is a comfortable 22.0 °C and 1.00 atm. At what relative humidity in your room does water vapor begin to condense on the window pane? Assume the inside air is uniformly 22.0 °C except for the air that is very close to the window, which has cooled to 7.3 °C. Solve for the relative humidity requested by first labeling the conditions on the diagram below. Put a label in each answer space, putting a numeric value if the number is given or implied above. Otherwise, use "unknown".
