Density — practice question

A student wants to find the density of a liquid. She transfers the liquid into a measuring cylinder, as shown in Fig. 1.1.
(a(i))[1]

State the value of the volume $V$ shown by the liquid in the measuring cylinder.

(a(ii))[1]

Her friend also measures the same volume of liquid in the measuring cylinder, but records a larger volume than the correct value in (a)(i). Suggest how this mistake is made.

(b(i))[1]

State one more piece of apparatus the student needs in order to determine the density of the liquid.

(b(ii))[2]

Explain in detail how she would use the apparatus to determine the density.

(c)[1]

Her friend also works out the density using her incorrect volume value. State how her density compares with the student's value.
