Waec Model Questions Vol1 2024 Physics Question 1 diagram

A student is required to determine the density of an unknown solid using the water‑displacement method. The apparatus consists of a digital balance, a beaker filled with water, and a graduated cylinder. The mass of the solid measured on the balance is 150.0 g. The initial water level in the graduated cylinder reads 200.0 mL and after the solid is completely immersed the level rises to 235.0 mL.

Question Parts

( a )

Calculate the volume of the solid in cubic centimetres.

( b )

Using the mass obtained, determine the density of the solid in g·cm⁻³ (give answer to two decimal places).

( c )

Comment on whether the material is likely to be a metal, given that typical metal densities lie between 7.0 and 19.0 g·cm⁻³.

( d )

Identify one possible source of systematic error in this experiment and explain qualitatively how it would affect the calculated density.
