Both Jars were placed in a controlled 90 degree fahrenheit and 50% humidity room. Film A became hazy with condensation and appeared as if it was getting sucked into the jar. Film B bubbled outwards from the Jar and did not have any visible condensation.
Which film was less permeable to water vapor?
2 jars filled with water are sealed with plastic film A & B. Which film transmits less water vapor?

More water condenses when pressure is reduced.
I might have that backwards.
Does the fact that condensation was visible inside of film A but not on film B play any role in the answer?
For instance, wouldn't the absence of condensation in jar B signify that water vapor was making its way out instead of being trapped inside?
