📌 Key Concepts
✦ Temperature = measure of hotness or coldness
✦ Our sense of touch is not reliable for measuring temperature
✦ Clinical thermometer: 35°C to 42°C (body temperature)
✦ Laboratory thermometer: −10°C to 110°C (experiments)
✦ Normal body temperature: 37°C (98.6°F)
✦ Digital thermometers are safer, faster, mercury-free
✦ Conversion: °F = (°C × 9/5) + 32; °C = (°F − 32) × 5/9

Q1
Normal temperature of a healthy human is close to:
ANSWER
Answer: (ii) 37.0°C (or 98.6°F).
Q2
37°C is same as:
ANSWER
Answer: (ii) 98.6°F
Conversion
°F = (°C × 9/5) + 32 = (37 × 9/5) + 32 = 66.6 + 32 = 98.6°F
Q3
Fill in the blanks.
ANSWER
| Statement | Answer |
|---|
| (i) Hotness or coldness is determined by its ______. | temperature |
| (ii) Temperature of ice-cold water cannot be measured by a ______ thermometer. | clinical |
| (iii) The unit of temperature is degree ______. | Celsius |
Q4
Range of a laboratory thermometer:
ANSWER
Answer: (ii) −10°C to 110°C
Q5
Can a clinical thermometer measure boiling water temperature?
ANSWER
No. Clinical range is only 35°C to 42°C. Boiling water is 100°C — it would damage the thermometer and may be dangerous.
Q6
Why is a lab thermometer not used for body temperature?
ANSWER
- Wider range (−10°C to 110°C) — less precise for body temp
- No kink/constriction — mercury falls back after removing
- Must be read while bulb stays immersed
Q7
Differentiate clinical and laboratory thermometers.
ANSWER
| Feature | Clinical | Laboratory |
|---|
| Range | 35°C to 42°C | −10°C to 110°C |
| Kink | Has a kink | No kink |
| Use | Body temperature | Experiments |
| Reading | After removing from body | While bulb is immersed |
Q8
Vaishnavi\'s temperature: (i) Highest? (ii) When? (iii) Normal when?
ANSWER
(i) Highest: 40.0°C
(ii) Day 1 at 7 PM
(iii) Returned to normal on Day 3
Q9
To measure 22.5°C, which thermometer?
ANSWER
Thermometer (b) — it has 0.5°C precision divisions. (a) has 1°C, (c) has 2°C steps.
Q10
Lab thermometer has 50 divisions between 0°C and 100°C. Each division = ?
ANSWER
100°C ÷ 50 = 2°C per division
Q11
Someone says fever is 101 degrees. Celsius or Fahrenheit? Convert.
ANSWER
It\'s Fahrenheit (101°C would be above boiling point — impossible for body).
°C = (101 − 32) × 5/9 = 69 × 5/9 = 38.3°C (mild fever; normal = 37°C).
Q12
Advantages of digital over mercury thermometers?
ANSWER
- No toxic mercury — safer
- Instant digital readings
- No parallax error
- If broken, no danger
- Beep sound when done
