Question 1 NECO_MODEL_QUESTIONS_VOL1 • 2017 • PHYSICS • practical

An irregular solid metal specimen is to be investigated for its density using the water‑displacement method. The mass of the dry specimen is measured with a balance and recorded. The specimen is then gently immersed in a graduated cylinder containing water and the rise in water level is noted.

Question Parts

( a )

Calculate the volume of the specimen from the water‑displacement readings.

( b )

Determine the density of the specimen in g cm⁻³.

( c )

The true density of the metal is known to be 8.50 g cm⁻³. Calculate the percentage error of the experimental value.

( d )

State two possible sources of error in this experiment and suggest one way to minimise each.
