• Liters

How can you determine the density of a liquid using a beaker?

• Measure the mass of the liquid directly

• Subtract the mass of the empty beaker from the total mass

• Use a ruler to measure the liquid's dimensions

• Estimate the volume visually

What principle did Archimedes use to determine the volume of an irregular object?

• Direct measurement

• Using a graduated cylinder

• Displacement of water

• Weighing the object

What does a specific gravity of 0.75 for oakwood indicate?
