Which method is used to measure the density of irregularly shaped objects?

• Displacement method

• Pycnometer method

• Hydrostatic weighing

• Spectroscopy

How can you determine the density of the material your house key is made of?

• Weigh the material, drop it into a test tube with water, read the volume, and use the formula density = mass/volume.

• Measure the length and width, calculate the area, and use the formula density = area/volume.

• Heat the material, measure the temperature change, and use the formula density = temperature/mass.

• Freeze the material, measure the ice formation, and use the formula density = ice/mass.
