Class 6 Science - ANDHRA-PRADESH
Temperature and its Measurement
In the Class 6 Science chapter 'Temperature and its Measurement', Andhra Pradesh (BSEAP) students learn about the concept of hotness and coldness, how to correctly measure temperature using thermometers, and the units used like Celsius and Fahrenheit. This chapter is fundamental for understanding thermodynamics and weather science in later classes. For board exams, students frequently face questions on reading thermometer scales, precautions during measurement, and the difference between laboratory and clinical thermometers. Mastering this chapter ensures a strong base in basic physics and everyday scientific observations.

Temperature
Temperature is a reliable measure of the hotness or coldness of an object, measured in units like Celsius.
Clinical Thermometer
A specialized glass thermometer used by doctors to measure human body temperature, typically ranging from 35°C to 42°C.
Laboratory Thermometer
A thermometer used in school and science labs to measure the temperature of various objects and liquids, usually ranging from -10°C to 110°C.
Transfer of Heat
Heat always flows naturally from a body at a higher temperature to a body at a lower temperature until both reach the same temperature.
Celsius Scale
The standard temperature scale where the freezing point of water is 0°C and the boiling point is 100°C.

Board Exam Info
In Andhra Pradesh (BSEAP) Class 6 Science examinations, this chapter typically carries around 4 to 6 marks. Common question types include short answers on precautions while using a clinical thermometer, differences between clinical and laboratory thermometers, and diagram-based questions.
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 it starts measuring accurately from a lower point.
Can we use a clinical thermometer to measure the temperature of boiling water?
No, because the temperature of boiling water is 100°C, which is far beyond the maximum limit (42°C) of a clinical thermometer, causing the glass bulb to break.
Why is mercury used in thermometers?
Mercury is used because it remains in liquid form over a wide temperature range, expands uniformly, and does not stick to the glass.
