Apiece of metal weighs 34 g in air. When it is immersed in a liquid of specific gravity 1.24 at 27 °C. it weighs 32 g. When the temperature of the liquid is raised to 42 °C. the metal piece weighs 31 g. Specific gravity of the liquid at 42 °C is 1.2. The coefficient of linear expansion of the metal is
