Welcome to Christine’s Corner! The spheres also contain liquid, but it changes density much less rapidly than the clear liquid in the thermometer, so it isn’t affected by the temperature change. In this case, you'll need to take the average value between the lowest bulb's temperature in the top group and the highest sphere in the bottom group (the spheres directly above and below the gap). Each bubble is also attached to a specific mass (labelled with the temperature it represents) to calibrate its density (the amount of mass in a given volume). My corner, my rules. However, as the interval between the medallions increases, more estimation comes into play, and thus more margin of error. $34.99 $ 34.
