If you were asked to convert 25 hg to the unit cg, which of the following would be the first fraction used in the conversion?

Hectograms are 10^2, and centigrams are 10^-2, so converting from hg to cg would require 25 to be multiplied by 10^4. Thus, the answer is 250,000 centigrams.

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.
