Detailed explanation-1: -Answer. Mercury thermometers cover a wide temperature range from −37 to 356 °C (−35 to 673 °F); the instrument’s upper temperature range may be extended though the introduction of an inert gas such as nitrogen.
Detailed explanation-2: -A clinical thermometer is a thermometer that is used to measure the temperature of the human body. A clinical thermometer has a temperature range of 35°C to 42°C.
Detailed explanation-3: -Mercury is a liquid that can flow but does not stick to the glass. Mercury is used in thermometers because It has a high coefficient of expansion so that even a small rise in temperature brings about sufficient expansion which can be detected in the capillary of the calibrated part of the thermometer.
Detailed explanation-4: -Updated On: 27-06-2022. Yes, we can measure temperature upto 500∘C with a mercury thermometer provided the space above mercury in thermomter is filled with nitrogen. This increases the boiling point of mercury.
