Question

is conversion of solid to liquid contraction or expansion​

Answer 1

EXPANSION.........

BECAUSE THE the molecules in solid are tightly packed which shows the contraction and the molecules in liquid are not so closely packed so it shows the expansion

Answer:

iN CASE OF WATER IT IS CONTRACTION. THIS PHENOMENON IS CALLED ANOMALOUS EXPANSION OF WATER.

BUT IN OTHER CASES(EXCEPT A FEW MORE ), IT IS EXPANSION. EG: WHEN SOLID COPPER ROD MELT , IT EXPANDS BUT WHEN ICE MELTS IT CONTRACTS.
