Question 1 NECO • 2023 • PHYSICS • essay

A student is required to determine the density of an irregular solid using the water‑displacement method in the laboratory. The apparatus consists of a graduated cylinder mounted on a stand, a balance, and the solid sample. The graduated cylinder is marked in millilitres (mL).

Question Parts

( a )

Describe the step‑by‑step procedure for measuring the density of the solid using water displacement, including how the mass of the solid is obtained.

( b )

The mass of the solid is measured as 45.0 g. When the solid is placed in the cylinder, the water level rises from 120.0 mL to 138.5 mL. Calculate the density of the solid, showing all intermediate steps and giving the final answer with the appropriate unit.

( c )

Identify two possible sources of error in this experiment and explain how each could affect the calculated density value.
