Brief Condensation Question

[rfer]

If I have a climate chamber - elevated temp and RF%, and have a sheet of transparent acrylic inside. Steady state conditions for both temp and humidity - so acrylic sheet is the same temp as air. Will condensation form on the clear acrylic sheet?

I am thinking condensation will not form on this sheet, but want to make sure.

If "elevated temperature" > dew point, no.

Good Luck,

Thank you. This makes sense.

Condensation requires an exchange of energy, usually driven by a temperature difference. It there is no difference in temperature between an object and the surrounding air there won't be condensation. Note that no difference is much different from really small difference, though annoying condensation usually requires large difference. There is also the chance for an air temperature change that produces fog which can deposit on things.

My favorite condensation problem was in the Gypsum caves in Mexico in which the temperature and humidity were high enough that the internal temperature of human lungs was enough to cause condensation - one could drown by just breathing, at least until the cave was closed and reflooded.

ETO sterilization preconditioning chamber; when you walk in you can only see for about 500ms after a blink because of the water condensing on your eyes.
