Temperature and its Measurement
Chapter: 10
| PART – II |
| IMPORTANT QUESTION ANSWER |
A. Answer the following Question:
(i) Why is the sense of touch not reliable for measuring temperature?
Ans: Because our hands can feel hot or cold differently based on prior exposure and cannot quantify exact temperature.
(ii) Why is a clinical thermometer range limited from 35°C to 42°C?
Ans: Because it is designed to measure human body temperature, which normally falls within this range.
(iii) Why do we use different thermometers for body temperature and other objects?
Ans: Because body temperature is within a small range, requiring precise measurement, while other objects may have a wider temperature range.
(iv) Who is Anna Mani and why is she important?
Ans: Anna Mani was an Indian scientist who developed weather instruments and contributed to renewable energy in India.
(v) What are the fixed points on the Celsius scale?
Ans: 0°C (freezing point of water) and 100°C (boiling point of water).
(vi) Why do thermometers use mercury or colored alcohol as the liquid inside?
Ans: Mercury and colored alcohol are used because they expand and contract uniformly with temperature changes, making them ideal for accurate temperature measurement. Mercury is especially useful because it remains liquid over a wide temperature range and provides a clear, visible reading.
(vii) How does the use of the Kelvin scale differ from the Celsius scale in temperature measurement?
Ans: The Kelvin scale starts at absolute zero (0 K), which is the lowest possible temperature where all molecular motion stops. The Celsius scale, on the other hand, starts at the freezing point of water (0°C). The Kelvin scale is commonly used in scientific work because it is based on absolute temperature, while the Celsius scale is based on the physical properties of water.
B. True or False:
1. The sense of touch is a reliable way to measure temperature.
Ans: False. (It varies based on prior exposure.)
2. The clinical thermometer can measure temperatures from 35°C to 42°C.
Ans: True.
3. The freezing point of water on the Celsius scale is 32°C.
Ans: False. (It is 0°C.)
4. Anna Mani contributed to developing weather instruments and renewable energy in India.
Ans: True.
5. The Kelvin scale is mainly used for measuring body temperature.
Ans: False. (The Kelvin scale is used for scientific work.)
