Laboratory Thermometer
Laboratory thermometers are used to measure the temperature of objects other than their own body temperature. It is a mercury thermometer whose calibration ranges from – 10°C to 110°C. Therefore, in order to measure the temperature of an object, it is necessary to know the value of a small part of the calibration done on it. The laboratory thermometer is shown in Figure.
Let us see how to measure the temperature of an object with a laboratory thermometer.

How to Measure Water Temperature with a Laboratory Thermometer
Take water in a vessel. Now take a laboratory thermometer and dip its knob in the water kept in the vessel in such a way that the knob does not touch the wall of the vessel and the thermometer remains vertical. Observe the movement of mercury in the thermometer. When the mercury in the thermometer is stable, take the reading of the thermometer. This will be the temperature of the water kept in that vessel.
Ask your friends also to take the heat of the water kept in the vessel. You will find that the reading taken by all your friends is not the same. To find out the reason, we use the following.
