What happens to the particles of a substance when it changes from a solid to a liquid? (2023)

Step 1: Start with a solid substance. In a solid, the particles are tightly packed together and held in fixed positions.
Step 2: When heat is applied to the solid, the particles begin to absorb energy.
Step 3: As the particles gain energy, they start to vibrate more quickly.
Step 4: With enough energy, the particles can overcome the forces that keep them in fixed positions.
Step 5: The particles then move apart from each other, allowing the solid to change into a liquid.
