A student measures the mass and the volume of four objects.
The Table shows the results.
Table
| Object | Mass in g\text{g}g | Volume in cm3\text{cm}^{3}cm3 | Density in g/cm3\text{g/cm}^{3}g/cm3 |
|---|---|---|---|
| wooden block | 600 | 1000 | 0.60 |
| candle | 45 | 50 | |
| plastic toy | 30 | 25 | |
| steel bolt | 79 | 10 | 7.9 |
Complete the Table.
The density of water is 1.0 g/cm3.
The student puts each object into a tank of water.
State which objects float.
Give a reason for your answer.
The student writes:
'Heavy objects sink in water and light objects float.'
Evaluate the student's statement.
Use data from the Table in your answer.
