Density: Required Practical.

Question 1

How to work out the density of a regular object?

Answer 1

• Measure the mass using a balance.
• Measure the lengths using a ruler and calculate the volume.
• Use the density equation to find the density.

Question 2

How do we work out the density of an irregular object?

Answer 2

• Measure the mass of the object using an balance.
• Fill a Eureka can with water.
• Place the object in the water. Causes water to be displaced and flow through the spout.
• Measure the volume of the water displaced- this is the volume of the object.
• Calculate density.
