Answer:
Option (D)
When a solid becomes a liquid, It changes shape but not volume
Step-by-step explanation:
When a solid is converted into a liquid, the shape of the liquid will changes allowing the tightly packed particles to expand and move freely and it conforms to shape of the container but the volume being fixed and definite.
The best example of this is melting of ice. When an ice cube is melted into water, the liquid state acquires the shape of the container in which it is kept and the volume remains fixed and constant.
