Question
Which substance is commonly used as a thermometric
material in thermometers due to its expansive properties under temperature changes?Solution
Mercury is extensively used in thermometers because it expands consistently with temperature changes and remains in liquid form at a wide range of temperatures, making it ideal for precise and reliable temperature measurements.
