(a)[1]
State the reason why two objects with the same temperature are said to be in thermal equilibrium.
(b(i))[1]
Suggest why mercury is a suitable liquid for measuring temperature across this range.
(b(ii))[2]
Suggest why water is not a suitable liquid for measuring temperature across this range.
(c(i))[1]
State the liquid’s boiling temperature, in $^\circ\text{C}$.
(c(ii))[4]
Determine the liquid’s specific heat capacity, in $\text{J g}^{-1}\text{K}^{-1}$.
(d)[2]
On Fig. 3.2, sketch how the water temperature changes with time $t$ from $t = 0$ to $t = 60\,\text{s}$. Numerical calculations are not needed.
