RP5 - Density - Part 2: Calculating the density of a irregularly shaped object.

Question 1

Outline the basic steps of the practical.

Answer 1

1. Measure the mass of the irregular shape
2. Fill a displacement can with water and submerge the object
3. Record the volume of water that has been displaced
4. Calculate the density from the mass and volume

Question 2

What should you place under the can spout to collect the water?

Answer 2

A measuring beaker.

Question 3

Explain how you should fill the displacement can to get the most accurate results.

Answer 3

Fill the can until water starts to drip out of the spout and into the beaker. Wait until the dripping just stops before submerging the object.
