Water was decomposed by the following reactions. Calculate the mass of HCl produced from 50.0 mL water assuming the following yields. (Density of water is 1.00 g/mL)
H2O → H2 + O2
90.0%

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.

Yes i think so not 100 percent sure though
