Experiment with a thermometer, clinical thermometer, the comparison of three kinds of liquid thermometer thermometer

Laboratory temperature with a thermometer, clinical thermometer, all belong to the liquid temperature thermometer, so all is the use of liquid working principle of heat bilges cold shrink. And the third kind of thermometer is the glass rod type, while the temperature of the liquid inside is different, laboratory is generally kerosene thermometer, clinical thermometer is the mercury, thermometer is alcohol. If these three kinds of liquid do not add pigment, are colorless, and glass rod is roughly similar, at this point that would not be good to distinguish between the three kinds of thermometer, so how to distinguish the three kinds of thermometer? Please see the table below: form and detailed lists of the three major differences, believe that as long as get a thermometer careful observation will be able to distinguish the three kind of thermometer, soon will know this is which kind of thermometer. Table just said the three differences on the structure of the thermometer, also it is because the structure of the different also led to the three different in the field of the use of the thermometer. Laboratory thermometer, just as its name implies is the thermometer used in the laboratory, used to measure the temperature of some materials in the laboratory. And a thermometer is everybody's most familiar thermometer, is widely used to measure the body temperature thermometer. Thermometer is also known as the maximum and minimum thermometer, can measure the maximum and minimum temperature within a certain time, is generally used in measuring indoor temperature at home; At the same time it is very common in the greenhouses, very popular among farmers and growers. The three kinds of thermometer difference in construction and application in the field of different is known to all, believe that will never confuse these three thermometer!
