Question
Give reason: Mercury is used in thermometers.
✓
Answer
Mercury is used in thermometers because it has a uniform rate of thermal expansion, which means it expands predictably with temperature changes, allowing for accurate temperature readings. Additionally, mercury remains in a liquid state over a wide range of temperatures, making it suitable for measuring both high and low temperatures.
