Practise measuring mass and volume for liquids, regular solids and sinking irregular solids, using dimensions or displacement before calculating density.
An irregularly shaped solid object has a density of 2.7 g/cm3.
Describe a method to measure the volume of the irregularly shaped solid object.
measure (initial) volume of liquid / water AND immerse object
OR
immerse object in a known / measured volume of liquid / water
B1
subtract initial / start volume from final / new volume
OR calculate the difference in volume
OR measure change in volume
B1
OR (alternative answer)
fill displacement can / container with water AND immerse object
(B1)
measure volume of displaced water
(B1)
