Explanation: A clinical thermometer measures human body temperature.
Question 6 of 15
The normal temperature of a healthy human body is about:
0°C
37°C
100°C
50°C
Explanation: Normal body temperature is about 37°C (98.6°F).
Question 7 of 15
The small bend near the bulb of a clinical thermometer is called a:
Kink
Scale
Bulb
Pole
Explanation: The kink stops the liquid slipping back so the reading can be taken.
Question 8 of 15

Clinical thermometer
Laboratory thermometer
Rain gauge
Compass
Explanation: A laboratory thermometer has a wide range for measuring other things.
Question 10 of 15

Explanation: 37°C equals 98.6°F, the normal body temperature.
Question 15 of 15
Scientists usually prefer the Celsius scale because its fixed points are:
32 and 212
Simple round numbers 0 and 100
Hard to remember
Always changing
Explanation: Celsius uses 0 (freezing) and 100 (boiling), which are easy to use.
