A cube made of metal of linear expansivity \(\alpha\) is heated through a temperature \(\theta\). If the initial volume of the cube is V_o, the correct expression for the increase in volume of the cube is

A relative density bottle of volume 50cm³ is completely filled with a liquid at 30^oC. It is then heated to 80^oC such that 0.75cm³ of the liquid is expelled. Calculate the apparent cubic expansivity of the liquid.
