Thermometers typically work by measuring changes in temperature through the expansion or contraction of a material, such as Mercury or alcohol, within a tube. As the temperature increases, the material expands and rises up the tube, allowing for an accurate reading. The scale on the thermometer is calibrated to correspond with specific temperature values based on known physical properties of the material used.

What are the factors on which responsiveness of thermometer depends upon?
The responsiveness of a thermometer depends on factors such as the size and material of the sensor, the speed of heat transfer within the system, and the efficiency of the electronics or mechanism used to measure and display the temperature. Additionally, the calibration and accuracy of the thermometer can also affect its responsiveness.
How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
What is the mechanism of a thermometer?
A thermometer typically consists of a temperature-sensitive element (such as mercury or a thermocouple) that expands or contracts with changes in temperature. This expansion or contraction is then converted into a temperature reading on a scale by mechanisms such as a bimetallic strip, a digital sensor, or a liquid crystal display.
What is the plural of thermometer?
The plural of thermometer is thermometers.
What do you call an ear thermometer?

What does the integrating center of a feedback mechanism resemble?
The Thermometer.

How does an ear thermometer measure the temperature?
An ear thermometer measures temperature by detecting the infrared heat emitted by the eardrum and surrounding tissue. The eardrum shares blood supply with the hypothalamus in the brain, which regulates body temperature. By measuring this infrared heat, the ear thermometer provides an accurate estimation of core body temperature.

What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
Why are bi-metallic thermometer helical shape?
The helical shape of a bi-metallic thermometer helps to amplify the movement of the jointed bi-metallic strip when temperature changes occur. This allows for a more accurate and visible indication of temperature fluctuations by increasing the sensitivity of the thermometer. Additionally, the helical shape provides support and protection to the delicate mechanism inside the thermometer.
