Question
Reema has a piece of modeling clay that weighs 120 g. She first moulds it into a compact cube of volume 60 cm³. Later, she flattens it into a thin sheet. Predict what will happen to its density.
Show answer
Answer
The density stays the same (2 g/cm³).
Explanation
Density
=
\( \dfrac{120\ \text{g}}{60\ \text{cm}^3} = 2\ \text{g/cm}^3 \)
- Flattening changes only the shape, not the mass or volume.
- Density does not depend on shape or size.
- So the density stays 2 g/cm³.
Reshaping does not change mass or volume, so the density remains 2 g/cm³.
