Questions with solutions
Q1 — Measuring Temperature · easy · theory
Which instrument is used to measure temperature?
A. Weighing balance
B. Thermometer ✓ Correct
C. Stopwatch
D. Ruler
Solution: A thermometer measures how hot or cold something is, that is, its temperature.
Q2 — Measuring Temperature · easy · theory
Which unit is commonly used to measure everyday temperature?
A. metre
B. second
C. degree Celsius (°C) ✓ Correct
D. kilogram
Solution: Everyday temperature is usually given in degrees Celsius (°C). Metre, kilogram and second measure length, mass and time.
Q3 — Measuring Temperature · easy · theory
The silvery liquid traditionally used inside a clinical thermometer is:
A. mercury ✓ Correct
B. water
C. milk
D. oil
Solution: A clinical thermometer traditionally uses mercury, a liquid metal that expands and rises evenly as the temperature increases.
Q4 — Measuring Temperature · easy · theory
The normal temperature of a healthy human body is about:
A. 100 °C
B. 37 °C ✓ Correct
C. 0 °C
D. 50 °C
Solution: A healthy person’s body temperature is about 37 °C. A much higher reading usually means the person has a fever.
Q5 — Measuring Temperature · medium · theory
At what temperature does water freeze into ice?
A. 50 °C
B. 0 °C ✓ Correct
C. 37 °C
D. 100 °C
Solution: Water freezes (turns to ice) at 0 °C. This is one of the fixed points used to mark a thermometer.
Q6 — Measuring Temperature · medium · theory
At what temperature does water boil (at sea level)?
A. 37 °C
B. 0 °C
C. 50 °C
D. 100 °C ✓ Correct
Solution: Water boils at 100 °C at sea level. This is the other fixed point used when marking a thermometer.
Q7 — Measuring Temperature · medium · theory
If the reading on a thermometer rises, it means the object has become:
A. colder
B. longer
C. heavier
D. hotter ✓ Correct
Solution: A higher temperature reading means the object is hotter. Temperature tells us how hot or cold something is, not its weight or length.
Q8 — Measuring Temperature · medium · theory
Why should you NOT measure the temperature of boiling water with an ordinary clinical (doctor’s) thermometer?
A. It has no numbers on it
B. It is too short
C. It measures length
D. Its scale only goes up to about 42 °C, so it may break ✓ Correct
Solution: A clinical thermometer reads only up to about 42 °C because body temperature stays low. Boiling water at 100 °C is far beyond its range and could break it.
Q9 — Measuring Temperature · hard · numerical
In the morning the temperature was 18 °C, and by noon it rose to 33 °C. By how many degrees did the temperature rise?
A. 15 °C ✓ Correct
B. 18 °C
C. 33 °C
D. 51 °C
Solution: The rise is the difference: 33 °C − 18 °C = 15 °C.
Q10 — Measuring Temperature · hard · theory
Besides the degree Celsius, another unit of temperature used in some countries is the degree:
A. Fahrenheit ✓ Correct
B. metre
C. Newton
D. litre
Solution: The degree Fahrenheit (°F) is another temperature unit, used in countries like the USA. Metre, litre and newton measure length, volume and force.
