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.
Why is it necessary for a clinical thermometer to have a bend?
The bend in a clinical thermometer allows the mercury or alcohol to stay in the measuring part of the thermometer for longer, ensuring an accurate reading. It prevents the column of liquid from dropping too quickly when removed from the body, providing a more stable and precise measurement.
How could you modify a experimental thermometer to read actual temperature?
To modify an experimental thermometer to read actual temperature, you would need to calibrate it against a known accurate reference thermometer. Compare the readings between the two thermometers at various temperatures and make necessary adjustments to ensure the experimental thermometer provides accurate readings. Recalibrate periodically to maintain accuracy.
What is the most accurate method for calibrating bimetallic thermometer?
The most accurate method for calibrating a bimetallic thermometer is to use a high-precision reference thermometer to compare and adjust the readings of the bimetallic thermometer at various temperatures. This process involves immersing both thermometers in a stable temperature source and recording the differences in readings to make necessary adjustments to the bimetallic thermometer's scale. Calibration should be performed at multiple points across the temperature range of interest to ensure accuracy.
What is the plural of thermometer?
The plural of thermometer is thermometers.
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 use a calibrated thermometer?
This is important for making correct measurements.

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 it is necessary to calibrate a thermometer and a volumetric glassware?
In order to get a more precise and accurate reading.

What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
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.
Origin of the word thermometer?
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.
