Does a thermometer measure heat or temperature explain?
Despite its name, however, a thermometer does not actually record heat, but rather temperature. Temperature is a measure of the average kinetic energy of the molecules within a substance.
Where do you measure a thermometer?
- Mouth: Place the probe under the tongue and close the mouth. Breathe through the nose.
- Rectum: This method is for infants and small children. They cannot hold a thermometer safely in their mouth.
- Armpit: Place the thermometer in the armpit. Press the arm against the body.
How does a thermometer measure body temperature?
Oral method (in the mouth)
- Carefully place the tip of the thermometer under your child’s tongue.
- With your child’s mouth closed, leave the thermometer in place for about 1 minute until you hear the “beep”
- Remove the thermometer and read the temperature.
Why the expansion of the glass of the thermometer is ignored?
The pressure of a constant volume of gas increases with temperature. The change in the length of the glass tube with variation in temperature is so small that we can ignore that and concentrate on the expansion of the volume of liquid in the bulb. As this volume expands it forces the liquid up into the glass tube.
What is range of normal body temp?
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.

Which type of thermometer is the most accurate?
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.
Is 99.1 a fever?
A factor that needs to be considered is how you took your temperature. If you measured your temperature under your armpit, then 99°F or higher indicates a fever. Temperature measured rectally or in the ear is a fever at 100.4°F (38°C) or greater. An oral temperature of 100°F (37.8° C) or more is a fever.
What are the two points used to calibrate a thermometer?
Answer: There are two points in a temperature scale,i.e, Upper fixed point and lower fixed point.
Is infrared a thermometer?
An infrared thermometer is a sensor that consists of a lens to focus the infrared (IR) energy on to a detector, which converts the energy to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation.
Is 100 a normal body temperature?
Normal Range A German doctor in the 19th century set the standard at 98.6 F, but more recent studies say the baseline for most people is closer to 98.2 F. For a typical adult, body temperature can be anywhere from 97 F to 99 F. Babies and children have a little higher range: 97.9 F to 100.4 F.
What is normal temperature for adults on forehead?
If you tell your doctor about your temperature reading, be sure to say where it was taken: on the forehead or in the mouth, rectum, armpit, or ear. Normal: The average normal temperature is 98.6°F (37°C).
