Question

As a solid melts to form liquid, which of the following effects take place?

• A. Inter particle distance increases
• B. Inter molecular forces of attraction decreases
• C. Compressibility increases
• D. All of the above

Answer 1

The correct option is D All of the above

When a solid melts, a state conversion is taking place. Intermolecular spaces of a solids are intact, the intermolecular space starts increasing when it starts getting extra energy and is converted to liquid. As the intermolecular space increases the intermolecular force of attraction is dominated by the increased energy of molecules which causes a change in state. Liquids have large intermolecular space hence they can be compressed more as compared to the solids.
