Q2
Difference in temperature = higher − ___ ?
Difference = higher temperature − lower temperature.
Q3
Which is colder, 5°C or 15°C?
5°C is the lower number, so it is colder.
Q4
Water boils at 100°C; it freezes at ___ ?
Water freezes at 0°C.
Q5
What is the difference between 38°C and 25°C?
38 − 25 = 13°C.
Q6
The temperature is 30°C and falls by 12°C. What is it now?
30 − 12 = 18°C.
Q7
The temperature is 22°C and rises by 9°C. What is it now?
22 + 9 = 31°C.
Q8
The temperature goes from 10°C to 35°C. By how much did it rise?
35 − 10 = 25°C.
Q9
What is the difference between 45°C and 19°C?
45 − 19 = 26°C.
Q10
It is 18°C in the morning and 29°C at noon. By how much did it rise?
29 − 18 = 11°C.
Q11
The temperature is 32°C in the day and 19°C at night. By how much did it fall?
32 − 19 = 13°C.
Q12
A patient's temperature is 39°C. Normal is 37°C. How much above normal is it?
39 − 37 = 2°C above normal.
Q13
Starting at 20°C, the temperature rises 3°C every hour. What is it after 4 hours?
3 × 4 = 12°C rise, so 20 + 12 = 32°C.
Q14
From 28°C the temperature falls 5°C and then rises 8°C. What is it now?
28 − 5 = 23, then 23 + 8 = 31°C.
