उत्तर
Water is not used as a thermometric liquid because It has a low coefficient of expansion so it is less sensitive to temperature changes. Moreover, It is transparent thus making it difficult to read the thermometer, and water evaporates with time thus producing an error, and also the freezing and boiling points are also low.
