Describe the structure of a thermometer?
The thermometer consists of a very fine glass tube having a very small bore and is called capillary tube. At one end of capillary tube a very thin glass bulb is provided. The bulb is filled with mercury( most of the times) or alcohol The other end of capillary tube is sealed. The capillary tube is protected by a thick glass tube called stem. On the stem are made markings. These markings are called graduations or degrees.
Why does a stem in clinical thermometer have a small cross section area?

What is the difference between a stem thermometer and a candy thermometer?
A stem thermometer is used to measure the internal temperatures of foods, especially meats. Stem thermometers have a "stem" that is inserted into the food and a flat round "face" at the top that may be digital or dail.
