(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.
