*MVTR stands for Moisture Vapor Transmission Rate in g-mil/100in. 2/24hr. MVTR is a measure of the passage of gaseous H2O through a barrier. The lower the rate, the longer the package protects its contents from moisture and ensures the moisture content of the product remains the same.
Isn't H2O in the gaseous state only when it has reached the temp. of boiling ?
Which is 212 degrees F or 100 degrees C at sea level and decreases as the altitude increases.
It seems to me that this would only be an issue if you brewed at something like 20,000 ft above sea level. Or you were to dump wort in at or near the boiling point.
Are the molecules of H2O that constitute relative humidity considered gaseous or still in the liquid form? I thought it was liquid althought they were contained within a gas.
I'm not a chemist but that seems pretty basic.
