Answer 1

The change that takes palace as solid turns to liquid is that particles become less ordered. That is option C.

What is change of state?

Change of state of a substance is the reversible changes that occurs in that substance which may include:

• melting,

• freezing,

• sublimation,

• deposition,

• condensation, and vaporization.

When a solid turns into liquid, it becomes less ordered because there is reduction of the intermolecular forces existing between the molecules of the substance.
