Question

What happens to particles in a solid when it is heated and begins to melt?
Options
A The particles stop moving
B The particles vibrate more strongly until attractive forces are no longer strong enough to hold them together
Correct Answer
C The particles immediately become gases
D The particles lose all attractive forces
Correct Answer

Option B is the correct answer.

Detailed Explanation

When a solid is heated, energy is transferred to the particles, causing them to vibrate more strongly. Melting occurs when the vibrations become so vigorous that the attractive forces holding the particles in fixed positions are no longer strong enough to keep them together.

Hint

Think about how added energy affects particle motion and intermolecular forces.
