What are the advantages and disadvantages of using alcohol in a glass thermometer?

Alcohol in a glass thermometer has several advantages, including a lower freezing point than Mercury, allowing it to measure colder temperatures without solidifying, and being less toxic, making it safer to handle. However, its disadvantages include a higher thermal expansion variability and lower accuracy compared to mercury, as well as a tendency to evaporate or form menisci, which can affect readings. Additionally, alcohol can stain and may require more frequent calibration.
