What in the world was recently based galileo s thermometer?
A Galileo thermometer, Galilean thermometer (named after Italian physicist Galileo Galilei), is a thermometer made of a sealed glass cylinder containing a clear liquid and a series of objects whose densities are designed to sink in sequence as the liquid is warmed and decreases in density and vice-versa. Typical design Suspended in the liquid are a number of weights. Commonly those weights are themselves attached to sealed glass bulbs containing colored liquid for an attractive effect. As the liquid in the cylinder changes temperature its density changes, and those bulbs are free to move, rising or falling to reach a position where their density is either equal to that of the surrounding liquid or where they are brought to a halt by other bulbs. If the bulbs differ in density by a very small amount and are ordered such that the least dense is at the top and most dense at the bottom, they can form a temperature scale. The temperature is typically read from an engraved metal disc on each
