Answer:
The particles have separated.
Explanation:
In a solid, the particles, (called molecules) are held close together in an orderly fashion with little freedom of motion. Molecules in a liquid are close together but are not held so rigidly in position and can move past one another.
Upon heating, a solid (a popsicle in this case) will melt to form a liquid . The temperature at which this change occurs is called the melting point.
