(a)[1]
Write down the mass $m$ of the block, accurate to one decimal place.
(b)[1]
Write down the volume $V$ of water illustrated in Fig. 2.2.
(c)[2]
The specific heat capacity $c$ of copper may be determined from the equation $c = \frac{V \times 4.2 \times (27 - \theta_1)}{m \times (100 - 27)}$. Use your results from (a) and (b), along with the value of $\theta_1$, to calculate $c$. State the unit for your answer.
(d)[1]
This method does not produce an accurate value for $c$. Suggest one reason for this.
