Answer 1

Melting

Step-by-step explanation:

From solid to liquid, the change of state happening is the melting process. The kinetic energy of the particles that makes up the solid is increased and it allows the liquid to flow.

• A solid is a fixed mass with static molecules.
• When thermal energy is added, the kinetic energy increases.
• The kinetic energy of the particles increases and they vibrate about their fixed point in solids.
• This eventually breaks the structure and liquid which begins to flow forms.

This is a melting process.
