The same sealed hollow plastic sphere is placed in two liquids. It comes to rest floating in each liquid.
| Liquid | Volume of liquid displaced in cm3\text{cm}^{3}cm3 |
|---|---|
| P | 420 |
| Q | 350 |
Explain what these measurements show about the density of liquid Q compared with the density of liquid P.
