How do chemical detectors that react upon being exposed to temperatures above or below a pre-set threshold work? Often found on the outside of temperature-sensitive shipping containers, the reaction causes a change in the color of the material. Some setups have the color change being permanent, in order to check for temperature continuity during the course of shipping. Are their liquids that react in similar fashion? In a separate note, what are some reactions that can be used for various given temperatures?

anything that is metal in a bathroom will form condensation because of the high humidity in there so it is normal for an a/c unit inside of a bathroom to sweat at times. often it is just the insulation inside of the unit next to the coil has come unglued and is no longer in contact with the metal so it gets too cool and forms condensation. next time the maint guy comes ask him to check this, in the mean time dry the unit well then cut a foam bord to cover the side panel of the unit and tape it in place. that should stop the problem
