How to rank the atoms in each group in order of increasing size?

a. Si, S, Mg: all in period 3, size decreases from left to right therefore S < Si < Mg b. Kr, Ne, Xe: all in group 18, size increases down a group therefore Ne < Kr < Xe c. B, C, Ne: all in period 2, size decreases from left to right therefore Ne < C < B

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.
