Answer:
Clinical thermometers are mostly used at homes. A clinical thermometer has a glass tube with a bulb at one end to measure temperature and it is closed at the other end. This bulb and some portion of the glass tube is filled with thermometric liquid such as mercury or alcohol. The rest of the volume of the tube has vacuum in it. There is a kink towards the end of the glass tube which keeps the thermometric liquid intact once it is removed from the hot body that is under observation. Such thermometers are basically used to measure the temperature of a human body. A clinical thermometer has a temperature range of 35ºC to 42°C only.
