Melting is defined as one of the physical processes in which the phase transition of a substance from solid to liquid takes place. The substance melt when it reaches the melting point.
The correct answer is:
Option B. They absorb heat energy and start moving more rapidly.
The mechanism of melting can be explained as:
1. Melting is the process of phase transition between the solid to liquid of a substance.
2. The ice cream bowls melt into a liquid state because the molecules of ice cream will absorb heat and start moving more rapidly.
3. As the molecules start moving rapidly, it causes the solid phase to change in the liquid phase of the substance.
Thus, the process is known as melting, when the substance absorbs heat and the molecules start to move more rapidly.
