a) The volume of a certain liquid varies with temperature as V=V^{\prime}\left\{0.75+3.9 \times 10^{-4}(T / \mathrm{K})+1.48 \times 10^{-6}(T / \mathrm{K})^{2}\right\} where V' is its volume at 300 K. Calculate its

expansion coefficient, ALPHA, at 320 K. E2D.3(b) The volume of a certain liquid varies with temperature as V=V^{\prime}\left\{0.77+3.7 \times 10^{-4}(T / \mathrm{K})+1.52 \times 10^{-6}(\mathrm{~T} / \mathrm{K})^{2}\right\} where V' is its volume at 298 K. Calculate its expansion coefficient, a, at 310 K.
