Product description
Description
Liquid thermometers manufactured according to the idea of Galileo Galilei (1564-1642).
Galileo discovered that liquids change their density depending on the temperature. If the temperature increases, the density of the liquid in the thermometer decreases. The comparatively heavier balls lose traction and fall. If the room temperature drops again on the other side, the lighter balls gain lift and rise gradually.
The difference in weight of the glass balls is measured (on a hundredth of a gram) exactly in such a way that always the lowest of the balls floating above is indicated in the range of the current temperature.Keywords
