Galileo Thermometer

The Galileo thermometer is a glass cylinder filled with a clear liquid and several glass spheres of different densities. As the temperature changes, the spheres rise or sink within the cylinder. The density of each sphere is calibrated to correspond to a specific temperature range. By observing which spheres are floating at a given time, one can approximate the ambient temperature. The Galileo thermometer operates on the principle of buoyancy, where changes in temperature affect the density of the liquid, causing the spheres to either float or sink based on their density relative to the liquid.

伽利略溫度計是一個充滿透明液體和幾個不同密度的玻璃球的玻璃圓柱體。 隨著溫度的變化，球體在圓柱體內上升或下沉。 每個球體的密度都經過校準，以對應於特定的溫度範圍。 透過觀察在給定時間哪些球體漂浮，可以估算出環境溫度。 伽利略溫度計的工作原理是浮力，溫度的變化會影響液體的密度，導致球體根據其相對於液體的密度而漂浮或下沉。
