A gallium thermometer is used to measure the temperature of the steel. It consists of a quartz glass bulb completely full of liquid gallium (gallium has a melting point of 302.9 K) with a volume of 0.5 cm³. This is connected to a vertical glass cylinder. If the volume expansivity of gallium is 1.2 × 104 K¹ and for quartz glass is 1.0 × 106 K¹, and the top of the gallium rises 2.1 cm for a 10 K increase in temperature, calculate the diameter of the cylinder. State any assumptions that you make to simplify your calculation. A gallium thermometer is used to measure the temperature of the steel.
