The element gallium (Ga) has the second-largest liquid rangeof any element, melting at 29.78 °C and boiling at 2204 °Cat atmospheric pressure. (a) What is the density of gallium in g / cm 3 at 25 °C if a 1 in.cube has a mass of 0.2 133 lb? (b) Assume that you construct a thermometer using galliumas the fluid instead of mercury and that you define the melting point of gallium as 0 °G and the boiling point of gallium as 1000 °G. What is the melting point of sodium chloride (801 °C) on the gallium scale?
