Why can mercury measure temperatures -38 to 350?

Mercury can measure temperatures between -38°C and 350°C due to its unique physical properties. It remains liquid at low temperatures, with a freezing point of -38.83°C, allowing it to accurately measure colder temperatures. Additionally, mercury has a high boiling point of 356.73°C, making it suitable for measuring higher temperatures without vaporizing. Its consistent thermal expansion also ensures precise readings within this range.
