Oral temperature is considered to be almost as accurate as rectal temperature. It’s the most common way to measure temperature in older children and adults. To take oral temperature, use a digital thermometer. Wait at least 30 minutes to use an oral thermometer if you’ve eaten or had something hot or cold.
Just so, how a thermometer is used to make measurements?
Liquid-filled thermometers have been used for centuries to measure temperature. They consist of a liquid-filled reservoir at the end of a narrow tube. If the temperature of the liquid in the reservoir increases, it expands and rises into the narrow tube.
- Under the armpit (axillary method)
- In the mouth (oral method)
- In the ear (tympanic method)
- In the rectum/bum (rectal method)
Hereof, what are the 3 main types of thermometers?
Types of thermometer
- Digital thermometers. Digital thermometers are quick to use, reasonably accurate and can be used under the armpit (always use the thermometer under the armpit with children under 5). …
- Ear (or tympanic) thermometers. …
- Infared thermometers. …
- Strip-type thermometers. …
- Mercury thermometers.
What are the three uses of thermometer?
– To measure the outdoor temperature. – To measure body temperature during a physical exam at the doctors. – To measure body temperature when someone is ill to determine if he/she has a fever. – To measure the temperature of an oven.
What are the two main types of thermometer?
Answer: two types of thermometers, namely, clinical thermometer and laboratory thermometer. Clinical thermometers are meant for clinical purposes. It is developed for measuring the human body temperature.
What is a thermometer used for in chemistry?
Thermometers measure temperature by using materials that expand or contract when heated or cooled. Mercury or alcohol thermometers, for example, have a reservoir of liquid that expands when heated and contracts when cooled, so the liquid column lengthens or shortens as the temperature of the liquid changes.
What is the temperature used for?
An object’s temperature is the best approximation of the kinetic energy of the particles. When we measure an object’s temperature, we measure the average kinetic energy of the particles in the object. The higher the temperature, the faster the molecules of the substance move, on the average.
What is thermometer and its types?
A thermometer is a device that is used to measure the temperature of a body. Common types of thermometers are Medical thermometers, Infrared thermometers, Mercury thermometers, thermocouple thermometers, laboratory thermometers, Bimetallic strip thermometers, Pyrometers, etc.
What is your normal body temperature?
The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.
What temp is a fever?
The following thermometer readings generally indicate a fever: Rectal, ear or temporal artery temperature of 100.4 (38 C) or higher. Oral temperature of 100 F (37.8 C) or higher. Armpit temperature of 99 F (37.2 C) or higher.
Where do we use thermometer?
The thermometer scans the surface of the forehead. These are sometimes used to screen for fever. If the temperature is higher than normal (greater than 101° F), it needs to be taken with a more accurate kind of thermometer. Temporal artery thermometers should not be used on infants.
Why mercury is used in thermometer?
Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. … It also has a high boiling point which makes it very suitable to measure higher temperatures. Also, it has a shiny appearance and doesn’t stick to the glass surface of glass.
