Class 6 Science - MAHARASHTRA
Temperature and its Measurement
In the Maharashtra State Board (MSBSHSE) Class 6 Science chapter 'Temperature and its Measurement', students explore the concepts of heat and temperature, understanding how they differ and how to measure them accurately. The chapter covers the working principle of laboratory and clinical thermometers, the units of measurement (Celsius and Fahrenheit), and safety precautions needed while handling glass thermometers. This topic forms the foundation for higher-level physics and chemistry, carrying significant weightage in board-related assessments through direct definitions, reading thermometer scales, and diagram-based questions.

Temperature
Temperature is a measure of how hot or cold an object is, which tells us the degree of heat in a body.
Clinical Thermometer
A specialized glass thermometer used specifically to measure human body temperature, typically ranging from 35°C to 42°C.
Laboratory Thermometer
A larger thermometer used in science laboratories to measure the temperature of various substances and liquids, usually ranging from -10°C to 110°C.
Units of Measurement
Temperature is commonly measured in degrees Celsius (°C) or degrees Fahrenheit (°F).
Normal Body Temperature
The average healthy human body temperature is approximately 37°C or 98.6°F.

Board Exam Info
This chapter typically carries 3 to 5 marks in Maharashtra (MSBSHSE) science evaluations. Common question types include labeling diagrams of thermometers, differentiating between clinical and laboratory thermometers, and answering short descriptive questions about temperature units.
Frequently Asked Questions
What is the difference between heat and temperature?
Heat is the total amount of thermal energy contained in an object, while temperature measures the intensity or how hot/cold the object is.
Why do we jerk a clinical thermometer before use?
We give it a jerk to lower the mercury level below 35°C so that it can measure the correct temperature accurately.
Can we use a clinical thermometer to measure boiling water?
No, because the temperature of boiling water is 100°C, which far exceeds the maximum range (42°C) of a clinical thermometer and will break it.
