Calculate the ph of a 0.281 m solution of ethylenediamine (h2nch2ch2nh2). the pka values for the acidic form of ethylenediamine ( h3nch2ch2nh3 ) are 6.848 (pka1) and 9.928 (pka2).

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.
