Important exam questions with answers
Can we always judge temperature by touch? Why or why not?
No, because our sense of touch depends on previous conditions and can give misleading results. For example, after placing one hand in warm water and the other in cold water, the same normal water feels different to each hand.
Why do we use thermometers instead of just touching to measure temperature?
Thermometers provide accurate and reliable measurements of temperature, unlike touch which only gives relative feelings. This helps avoid mistakes and gives exact temperature readings.
Explain why metal feels colder than wood even when both are at the same temperature.
Metal conducts heat faster than wood, so it draws heat away from the skin quickly, making it feel colder. Wood is an insulator and does not conduct heat as fast, so it feels warmer.
Hindi explanation
शिलांग की ठंडी शाम में लम्बोक को बुखार महसूस होता है। उसकी बहन फिबन ने स्पर्श पर भरोसा न करके थर्मामीटर से तापमान मापा। यह अध्याय हमें सिखाता है कि तापमान को सही मापना क्यों जरूरी है और स्पर्श से हमेशा सही पता नहीं चलता।
FAQ
Why can't we trust our sense of touch to measure temperature accurately?
Because touch depends on previous temperature exposure and can be misleading; for accurate measurement, thermometers are used. You can listen to the full explanation on Harshali Academy.
How does a thermometer work to measure temperature?
A thermometer measures the degree of heat or cold by showing a numerical value, giving an exact temperature reading. Harshali Academy’s audio lessons explain this clearly.
What should students remember about temperature measurement for exams?
Students should remember that touch is not reliable for judging temperature and thermometers are used for accurate measurement. Harshali Academy provides detailed exam notes to help.
How can this chapter help parents evaluate their child's learning?
The chapter explains scientific concepts with relatable examples, helping parents understand how their child learns about temperature measurement. Harshali Academy’s audio lessons make it easy to follow.
What teaching aids can teachers use from this chapter?
Teachers can use the hand-in-water experiment and real-life examples from the chapter to demonstrate why accurate measurement matters. Harshali Academy offers audio content that supports these teaching points.
