    2) Barometer has a function to forcast the weather changes through air pressure.
    3) Galileo thermometer can measure the current temperature through the tage below the glass balls.
    4) The glass balls differ in weight and the density of the liquid means the lowest of the floating ball in the upper part          of the cylinder shows the accurate temperature.
    5) In liquid, solid substances with the same weight and size sink when temperature rises, and they ascend when          temperature falls.
