molecules are more closely packed in solid state
B
ice crystals have hollow hexagonal arrangement of 
molecules
molecules
C
on melting ofice the 
molecules shrinks in size
molecules shrinks in size
D
ice forms mostly heavy water on first melting. ( 1992 )
Text Solution
Verified by ExpertsThe correct answer is:
B
: In ice crystals, water molecules are linked through 
‐ bonds in hollow hexagonal arrangement so, volume is large and density is less. In liquid state this hollow arrangement breaks into more closer arrangement of molecules. Consequently the density is increased in liquid state.
