Make *ure to be specific (2pt)

Explanation / Answer

29. triple point is that temperature and pressure at which all the states of the compound exists in equillibrium.

eg . triple point of water .010cand pressure 4.58mm of Hg

30 , because of less size and non availability of d orbital it is less electronegative. hence hydrogen can form hydrogen bonds with electronegative elements like O,F,N etc.
