How to read laboratory thermometer
Answers
Answer:
The thermometer is washed with water at normal temperature.
The temperature difference indicated between two bigger marks is noted.
Laboratory Thermometer
Since clinical thermometers can’t be used to measure temperature other than the human body, we need a special type of thermometers for other purposes. A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature. It ranges from -10˚C to 110˚C.
Laboratory thermometers are designed for lab purposes such as checking boiling point, freezing point, or temperature of other substances. You can use a laboratory thermometer for checking the temperature of a solvent but not a clinical one.

Explanation:
et up the stand. Typically, laboratory stands are of simple construction, with a thick, heavy base (usually of metal) and a long, thin bar extending upward. Depending upon your experiment, you may have to alter where your stand is positioned. For example, if you are using a Bunsen burner, you may have the legs of the stand straddling the burner, but if you are weighing a material as it undergoes temperature change, the stand's base can face away from the scale.
Attach the clamp to the stand. The clamp has two ends: The first is a rubberized end that will hold the thermometer, and the other is a C-shaped end with a bolt through it. Unscrew the bolt and fit the clamp onto the stand. Tighten the clamp before moving on.
Attach the thermometer. Fit the thermometer into the rubberized end of the clamp. Tighten the screw to secure the thermometer.
Place the end of the thermometer with the reservoir of liquid in the testing medium. For example, if you are testing the temperature of ice water, place the reservoir in the water, below the ice, but not touching the bottom of the flask or cup the water is held in. This will garner a more accurate temperature.
Interpret the readings.
