Question

in solidification inter molecular space dicreases why​

Answer 1

Answer:

Intermolecular space, by definition, is the empty space between the molecules of any substance.

As the intermolecular space reduces, a substance, if gas, gradually becomes liquid and then solid.

As to answer your question, if intermolecular space of liquids is reduced, the substance gradually becomes solid as the density increases.

Intermolecular space can be reduced by two methods:

Cooling ( reducing temperature )

By applying pressure.

Answer 2

As the intermolecular space reduces, a substance, if gas, gradually becomes liquid and then solid.
