All 'old' thermometers measure temperature as a difference between the thermal expansion of two substances.
Every substance expands at a slightly different rate. Mercury, for example, expands at a large and consistent rate; while glass hardly expands at all. This makes them a very accurate combination in a thermometer (at low temperatures, -20 to 150 deg C 'ish).
Other thermometers use two strips of different metals stuck together, like a double layered cake. When heated or cooled one strip expands more than the other so the strips will curl, the amount of curl indicates how much the temperature has changed.
The best substances for 'old' thermometers have a high (fast) thermal conductivity.
Modern inferred (laser) thermometers measure the amount of heat being emitted by an object. Essentially it measures the total energy of photons being emitted by a given area. NB. the laser is just used to help aim the thermometer; it plays no part in the actual measurement.

How do themometers work?
Thermometers work by measuring temperature using a temperature-sensitive component, like a liquid, gas, or a digital sensor. When the temperature changes, the component inside the thermometer expands or contracts, and this change is indicated on a scale as a temperature reading.
Temperature is a measure of what of the particles in an object?
degrees Temperature is a measure of heat in an object.
What are the properties that a device must have in order to measure temperature?
A device that measures temperature must have a temperature sensor that responds to changes in temperature, a way to convert the sensor's response into a numerical value, and a display or output to show the numerical temperature value. Additionally, the device should have the ability to calibrate and accurately measure a range of temperatures.
How do you describe the way in which thermometers measure temperature?
Thermometers measure temperature by detecting changes in a material (like mercury or alcohol) caused by heat. As the temperature increases, the molecules in the material move more quickly, causing it to expand and rise in the thermometer tube. This expansion is calibrated against a scale to give a temperature reading.
What is the name of the equipment that measure temperature?
A device used to measure temperature is called a thermometer.
Why were themometers invented?
Thermometers were invented to measure temperature accurately in various settings such as in the medical field, scientific research, and industrial processes. They provide a standardized way to quantify and monitor changes in temperature, allowing for better control and understanding of thermal conditions.
What is temperature scale of most laboratory themometers?
Celsius.
Is Jupiter's temperature ferienheight or Celsius?
When we measure Jupiter's temperature, we can describe it either way.
What is the liquid metal that is sometimes used in themometers?
Mercury.
The kelvin scale is used to measure what?
The Kelvin scale is used to measure absolute temperature, i.e., temperature from absolute zero. The way it is defined, there are no negative temperatures on the Kelvin scale.The Kelvin scale is used to measure absolute temperature, i.e., temperature from absolute zero.

What is the English way to measure temperature?
The English reason for measuring temperature is no different to that for any non-English person.
When you measure the temperature of an object you measure the?
Temperature xD
What are the two things that are found in themometers?
Meow Mix and Vacuum cleaners
How were themometers made smaller?
By using denser mercury instead of ethanol.
What instrument do you temperature with?
measure temperature? A thermometer.
Why is it necessary to use a thermometer to measure temperature?
If you do not use a thermometer to measure temperature, then you have no way of knowing exactly what the temperature is, either of the air, or of the turkey you are baking, or of your refrigerator, or of your own body (if you have a fever) or of various other things for which you might have a reason to want to know the temperature.
Must temperature be measured in the shade?
The answer depends on why you want to measure the temperature and what the object is. I cannot see any way of measuring the temperature of the surface of the sun in the shade!
