Questions: What happens to the particles when melting occurs? The particles move slower. The particles move faster. The particles line up.

Solution Steps

Melting is the process where a solid turns into a liquid. This occurs when the solid is heated to its melting point, causing the particles to gain energy.

As the solid is heated, the particles absorb energy and their kinetic energy increases. This causes the particles to vibrate more vigorously and eventually break free from their fixed positions in the solid structure.

Given the options:

• The particles move slower.
• The particles move faster.
• The particles line up.

The correct statement is that the particles move faster as they gain energy and transition from a solid to a liquid state.
