Temperature
Temperature is a reliable measure of the degree of hotness or coldness of an object.
Clinical Thermometer
A specialized glass thermometer used to measure the human body temperature, typically ranging from 35°C to 42°C.
Laboratory Thermometer
A scientific instrument used to measure the temperature of various objects and liquids in a school laboratory, usually ranging from -10°C to 110°C.
Celsius Scale
The standard international scale used for measuring temperature, denoted by the degree symbol (°C).
Transfer of Heat
Heat always flows naturally from a hotter body to a colder body until both reach the same temperature.

Board Exam Info
In the Telangana (TSBSE) Class 6 Science examinations, this chapter typically carries around 4 to 6 marks. Questions frequently include diagram labeling of thermometers, short answers on precautions while using a clinical thermometer, and differentiating between clinical and laboratory thermometers.
Frequently Asked Questions
Why do we jerk a clinical thermometer before use?
We jerk a clinical thermometer to bring the level of mercury down below 35°C so that it starts measuring from a lower point.
Can we use a laboratory thermometer to measure human body temperature?
No, because the moment you take a laboratory thermometer out of the mouth, the mercury level starts falling rapidly as it lacks a constriction.
What is the normal temperature of a human body?
The normal temperature of a healthy human body is 37°C (degree Celsius).
