Thermometers show body temperature in either degrees Fahrenheit (°F) or degrees Celsius (°C). In the United States, temperatures are often measured in degrees Fahrenheit.
What can be found in a thermometer?
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
What is the limit of thermometer?
They have scale divisions of 0.5°C and various measurement limits—the lower limit may be –75°, –65°, or –60°C, and the upper limit may be 20° or 25°C. Mercury-filled maximum-registration meteorological thermometers are used to measure the maximum temperature over a given time period.
Which information can you learn by reading a thermometer?
It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin.
Which type of thermometer is the most accurate?
Digital thermometers
Digital thermometers are the most accurate way to take body temperature. There are many types, including oral, rectal, and forehead, plus many that are multifunctional. Once you decide on the type of thermometer you want, you can think about design, extra features, and price.
What is the best time of day to take your temperature?
Body temperature varies throughout the day and is lowest in the morning and highest in the afternoon. Your body has a complex thermoregulation mechanism to help keep its temperature within the normal ranges. There really isn’t a “best time of day” to check your temperature.
Who uses thermometer?
Meteorologists use thermometers to find out how hot it is or if it’s below freezing. Doctors use thermometers to check your body temperature — a very high or low body temperature means you’re sick.
What is the end of a thermometer called?
Capillary Tube The capillary of a mercury thermometer is the long cylindrical tube that is connected to the bulb. As temperature increases, mercury flows up the capillary. The further the mercury moves up the capillary, the higher the measured temperature. The capillary ends in a section known as the expansion chamber.
What is maximum thermometer used for?
maximum thermometer A thermometer that records the highest temperature to which it has been exposed (e.g. by allowing a rise of mercury past a restriction in the tube, but preventing the mercury’s return on contraction). It is most commonly used to record maximum daily temperatures.
Where is maximum and minimum thermometer used?
Maximum/minimum thermometers are often used to measure a maximum/minimum air temperature for example in a greenhouse. Thus, the transfer liquid should preferably remain substantially liquid up to and above the highest expected temperature.
Is 25 degree Celsius hot or cold?
Temperature
| Temperature °C | What might be at this temperature | How it feels |
|---|---|---|
| 10 | Cold | |
| 15 | Cool | |
| 20 | Room indoors | Warm |
| 25 | Warm room | Warm to hot |
Which is more accurate mercury or digital thermometer?
The digital thermometer is not only faster on body temperature measurement results providing, but also better accuracy results to us. Based on the tested records of the experiments, the accuracy of a digital thermometer could be 0.1℃. The accuracy is better than the normal mercury thermometer.

Where is the thermometer in the human body?
Medical thermometer. A medical thermometer (also called clinical thermometer) is used for measuring human or animal body temperature. The tip of the thermometer is inserted into the mouth under the tongue ( oral or sub-lingual temperature ), under the armpit ( axillary temperature ), or into the rectum via the anus ( rectal temperature ).
Where can I get a digital thermometer to take my temperature?
Using a digital thermometer. You can get fast and accurate readings with digital thermometers. They are available in many shapes and sizes at grocery stores, department stores, and drug stores. You can use a digital thermometer in 3 ways: Oral (in the mouth). Rectal (in the bottom). Axillary (under the arm).
Do you need a thermometer to take an oral temperature?
Digital thermometers. For older children and adults, oral readings are usually accurate — as long as the mouth is closed while the thermometer is in place. If you plan to use a digital thermometer to take both oral and rectal temperatures, you’ll need to get two digital thermometers and label one for oral use and one for rectal use.
