Reading Thermometers worksheet with nine thermometers displaying different temperature values.

Explanation:
We need to read the temperature on each thermometer. Each thermometer has a scale with numbers and small lines (graduations). Let’s figure out how much each small line represents.

Looking at the first thermometer (a):
- The numbers shown are 60, 70, 80 — so each big mark is 10 units apart.
- Between 60 and 70, there are 10 small lines → each small line = 1°C (or 1 unit).
- The black liquid (mercury/alcohol) ends at the 4th line above 60 → 60 + 4 = 64.

But wait — let’s double-check all thermometers carefully, because some may be negative or have different scales.

Let’s go one by one:

a) Scale: 60 to 80, labeled every 10. Liquid top is at 4 marks above 60 → 64

b) Scale: -10 to 10 (zero in middle). Liquid top is at 2 marks *below* zero → –2

c) Scale: 0 to 20. Liquid top is at 12 (12 marks above 0, since 0–10 is 10 lines, then 2 more) → 12

d) Scale: –10 to 10. Liquid top is at 3 marks *above* zero → +3

e) Scale: 25 to 29? Wait — labels: bottom is 25, then 26, 27, 28, 29 — each big number is 1 unit apart, and there are no smaller ticks between them? Actually, looking closely: the scale shows 25, 26, 27, 28, 29 — and the liquid ends exactly at the line labeled 27 → 27

f) Scale: 0 to 30, labeled every 10. Between 0 and 10: 10 small lines → each = 1. Liquid ends at 2 marks below 10 → 10 – 2 = 8

Wait — no, look again: In f), the liquid goes up to just below 10 — actually, counting from 0: 0, then 10 small lines to 10. The top of liquid is at the 8th line → 8

g) Scale: –20 to 20? Labels: –20, –10, 0, 10, 20. Between –10 and 0: 10 small lines → each = 1. Liquid ends at 3 lines above –10 → –10 + 3 = –7

Wait — check: from –10 upward, 1st line = –9, 2nd = –8, 3rd = –7 → yes, –7

h) Scale: –15 to 5. Labeled –15, –10, –5, 0, 5. Between –10 and –5: 5 small lines? Actually, standard is 10 small lines per 5-degree interval? No — better to count spacing.

Look at h): The markings are every 1 unit (since –15 to –10 is 5 units, and there are 5 small intervals → each = 1). Liquid ends at 2 lines *above* –15 → –15 + 2 = –13

Wait — but the black column goes up to the line just above –15 — let’s count: from bottom (–15), first tick = –14, second = –13. Yes, top of liquid is at –13

i) Scale: 15 to 30? Labels: 15, 20, 25, 30. Between 20 and 25: 5 small lines → each = 1. Liquid ends at 3 lines above 20 → 20 + 3 = 23

Wait — but looking at i), the liquid reaches the line labeled 23? Actually, the scale shows 20, then 21, 22, 23, 24, 25 — yes, it's at 23

Let me verify each using consistent method:

Standard rule: If two labeled numbers differ by N, and there are M small divisions between them, each division = N/M.

Most thermometers here use 10 small lines per 10-degree interval → 1° per line.

Now list all clearly:

a) 60 to 70 = 10°, 10 lines → 1°/line. Liquid at 4 above 60 → 64

b) –10 to 0 = 10°, 10 lines. Liquid at 2 below 0 → –2

c) 0 to 10 = 10°, 10 lines. Liquid at 12? Wait — the top is above 10? No, scale goes to 20, and liquid stops at the 12th line from 0 → yes, 12

d) –10 to 0 to 10. Liquid at 3 above 0 → 3

e) Labeled 25, 26, 27, 28, 29 — liquid exactly at 27 → 27

f) 0 to 10: 10 lines; liquid at 8th line → 8

g) –20 to –10 to 0. From –10, up 3 lines → –7 → –7

h) Labels: –15, –10, –5, 0, 5. From –15, up 2 lines → –13 → –13

i) Labels: 15, 20, 25, 30. From 20, up 3 lines → 23 → 23

All match.

Final Answer:
a) 64
b) –2
c) 12
d) 3
e) 27
f) 8
g) –7
h) –13
i) 23
