Density Measurement
Will it Float or Sink?
|
|
High school students in a physics class
are asked to measure the mass and volume of two unknown liquids.
The raw data collected are summarized in the following table:
|
Empty Container Mass (g) |
Container & Liquid Mass (g) |
Volume of Liquid (ml) |
Liquid A |
25.0 |
75.0 |
50 |
Liquid B |
25.0 |
44.7 |
25 |

Questions
|
|
Determine the densities of the two liquids,
and identify the liquids. Also, predict if an ice cube and a cork
will sink or float in the two liquids.
|
|
|
|
Approach
|
|
- The density of the ice cube is 900 kg/m3, and the
density of the cork is 250 kg/m3.
