Why is it necessary to insulate the bulb on the thermometer went taking the superheat of an evaporator?
So you can get a correct reading
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 instrument measures how hot or cold something is?
A thermometer is an instrument that measures cold and heat, together with temperature variations.
Who is the inventor thermometer?
thermometer
What is a glass bulb of a thermometer?
thermometer
How can you use the words inquiry and thermometer in one sentence?
I did not understand the nurse's inquiry as to what I had done with the thermometer. Will an inquiry be necessary to find that thermometer? A silent thermometer has no inquiry.
Why is it necessary to warm the thermometer before placing it into the solutions?
The thermometer reading will change from reading the solution temperature.
Why is it necessary to use a calibrated thermometer?
This is important for making correct measurements.

Why it is necessary to calibrate a thermometer and a volumetric glassware?
In order to get a more precise and accurate reading.
What is meant by the statement a thermometer measures its own temperature?
When a thermometer reaches thermal equilibrium, the temperature of the thermometer and the substance it is measuring are the same. Therefore, the thermometer is essentially measuring its own temperature.
What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
Origin of the word thermometer?
Thermometer
What instrument measures hot or cold air?
a thermometer
Why is thermometer usually shakes before using?
It isn't necessary with new electronic thermometers, but if you still have an old hold-under-your-tongue-for-three-minutes mercury thermometer, the mercury will remain at the last recorded temperature until it is shaken back into the reservoir.
