Reading Thermometers Walkthrough - Free Printable

It looks like you've uploaded a screenshot of a temperature reading task involving thermometers. The image shows several thermometers labeled d), e), f), g), h), and i), with some already filled in and others left blank for you to solve.

Let’s go through each one step by step, interpreting the temperature readings based on the scale and the position of the mercury (or indicator line).

---

Understanding the Scale:

Each thermometer has a vertical scale marked in degrees Celsius (°C). The key is to:

1. Identify the range and increments.
2. Find where the indicator (the black line) is pointing.
3. Read the value accurately.

d)

- Scale: From -20°C to 20°C
- Increments: Each small tick = 2°C (since from -20 to -10 is 10°C divided into 5 ticks → 2°C per tick)
- Indicator is between -10 and 0, closer to -10.
- It's at the first tick below -10, so:
- -10 - 2 = -12°C
- But the answer written is -11°C — that suggests a possible error or different interpretation.

Wait — let’s double-check.

If the spacing is 1°C per tick, then:

- Between -10 and 0 there are 10 ticks? No, visually it seems like:
- From -20 to -10: 5 ticks → 2°C per tick
- So -10, -8, -6, -4, -2, 0

But the indicator is just below -10, and appears to be halfway between -10 and -12?

Wait — actually, looking closely, the indicator is just above -10, but not quite at -10.

Wait — no. Let’s look again.

Actually, the indicator is aligned with the first tick below -10, which would be -12°C if each tick is 2°C.

But the handwritten answer says -11°C, which implies 1°C per tick.

So perhaps the scale is 1°C per tick.

Let’s re-analyze:

From -20 to 20, with marks every 10°C, and smaller ticks in between.

Between -10 and 0: there are 10 small ticks → so each tick is 1°C.

Yes! That makes sense.

So:
- Each small tick = 1°C
- The indicator is one tick below -10, so:
- -10 - 1 = -11°C ✔

So d) = -11°C — correct.

---

e)

- Scale: From -15 to 5°C
- Increments: Each small tick = 1°C
- Indicator is between 0 and -5, specifically above -10, but wait — it's near the top.

Wait — the indicator is just below 0, and appears to be at -1°C?

But the handwritten answer says 28.1°C — that doesn't match this scale!

Wait — this is confusing.

Let’s check the scale labels:

In e), the top is labeled 23°C, and the scale goes down to -15°C.

Wait — the top of the scale is 23°C, and it decreases downward.

So the top is 23°C, then 20, 15, 10, 5, 0, -5, -10, -15.

But the indicator is just below 0, so around -1°C?

But the handwritten answer says 28.1°C — that can’t be right.

Wait — maybe the scale is not decreasing?

No — typically, thermometers have higher values at the top.

But here, the label "23°C" is at the top, and the scale goes down to -15°C.

So the indicator is at the bottom, near -10 or -15?

No — the indicator is just below 0, so around -1°C.

But the handwritten answer says 28.1°C — that’s impossible unless the scale is mislabeled.

Wait — perhaps the label "23°C" is not part of the scale, but an example?

Looking at the layout:

There are three small thermometers at the top: labeled d), e), f), with answers written next to them.

Then below, larger thermometers labeled d), e), f), g), h), i).

But the large ones are separate.

Wait — perhaps the top row is examples, and the bottom row is the actual problem?

Let’s clarify:

- Top row: d), e), f) — with answers written: -11°C, 28.1°C, 16.0°C
- Bottom row: d), e), f), g), h), i) — these are the thermometers to read

So the bottom row is the actual task.

So we need to read g), h), i) — since d), e), f) are already done.

But the user wrote: “solve the problem” — so likely, g), h), i) are blank.

Let’s focus on g), h), i).

---

g)

- Scale: From -20 to 20°C
- Increments: Each tick = 2°C (from -20 to -10: 5 ticks → 2°C each)
- Indicator is between 0 and 10, closer to 10
- It's at the third tick above 0?
- 0, 2, 4, 6, 8, 10
- Wait — the indicator is at 8°C?

But let’s count:

- From 0 up: 2, 4, 6, 8, 10
- The indicator is just below 10, but at the second tick above 8?

Wait — no, the indicator is aligned with the tick at 8°C?

Actually, the indicator is at the third tick above 0, which is 6°C?

Wait — let’s look carefully.

The scale has:
- 20, 10, 0, -10, -20

And between each 10°C, there are 5 small ticks → so each tick = 2°C

So:
- Below 0: -2, -4, -6, -8, -10
- Above 0: 2, 4, 6, 8, 10

Now, the indicator is just above 0, and appears to be at the second tick above 0, which is 4°C

But wait — the indicator is at the fourth tick above 0, which is 8°C

Yes — the black line is at the 8°C mark

So g) = 8°C

But let’s confirm:

- 0 → first tick: 2°C
- Second: 4°C
- Third: 6°C
- Fourth: 8°C
- Fifth: 10°C

Indicator is at the fourth tick above 0, so 8°C

✔ g) = 8°C

---

h)

- Scale: From -15 to 5°C
- Increments: Each tick = 1°C
- Indicator is between -10 and -5, closer to -10
- Specifically, it's at the second tick below -10, so:
- -10, -11, -12 → wait, no

Wait — the scale goes from -15 to 5, with marks at -15, -10, -5, 0, 5

Between -15 and -10: 5 ticks → so each tick = 1°C

So:
- -15, -14, -13, -12, -11, -10

Indicator is just below -10, at -11°C

Wait — no — the indicator is at the tick just below -10, which is -11°C

But let’s see — the black line is at the first tick below -10, so -11°C

But wait — is it?

Actually, the indicator is at the level of -10, but slightly below?

No — it's clearly at the first tick below -10, so -11°C

But wait — the scale goes down to -15, and the indicator is near the bottom, but not at -15.

Wait — looking at the image:

The indicator is just above -10, and appears to be at -9°C?

Wait — no.

Let’s count:

- From -15 to -10: 5 ticks → each 1°C
- So: -15, -14, -13, -12, -11, -10

The indicator is at the third tick above -15, so:

- -15 → 0
- -14 → 1
- -13 → 2
- -12 → 3
- -11 → 4
- -10 → 5

But the indicator is at the tick just below -10, so -11°C

Wait — but visually, it looks like it's at -10, but no — it's slightly below.

Actually, upon close inspection, the indicator is at the same level as -10, but the black line is exactly at -10°C

Wait — no — the black line is just below -10, so -11°C

But let’s assume the scale is accurate.

Alternatively, perhaps the indicator is at -10°C.

But it’s slightly below.

Wait — the indicator is at the tick labeled -10, so -10°C

But the tick labeled -10 is present, and the black line is at that tick.

Yes — the black line aligns with the -10°C mark.

So h) = -10°C

Wait — but earlier I thought it was below.

Let me recheck.

Looking at the image: the indicator is at the horizontal line labeled -10, so yes — -10°C

✔ h) = -10°C

---

i)

- Scale: From 96 to 100°C
- Increments: Each tick = 1°C (since 96, 97, 98, 99, 100)
- Indicator is between 98 and 99, closer to 98
- It's at the second tick above 98, so:
- 98, 98.2, 98.4, 98.6, 98.8, 99

But the scale has small ticks between 98 and 99 — probably 5 ticks → so each tick = 0.2°C

So:
- 98.0, 98.2, 98.4, 98.6, 98.8, 99.0

The indicator is at the third tick above 98, so 98.6°C

But let’s see — the black line is at the third tick after 98, so:

- First tick: 98.2
- Second: 98.4
- Third: 98.6

Yes.

So i) = 98.6°C

But wait — the scale may have only 1°C increments.

Wait — between 98 and 99, there are 5 small ticks, so:

- 98.0 → 98.2 → 98.4 → 98.6 → 98.8 → 99.0

So yes, each tick = 0.2°C

Indicator is at 98.6°C

✔ i) = 98.6°C

---

Final Answers:

- g) = 8°C
- h) = -10°C
- i) = 98.6°C

---

Summary:

| Thermometer | Temperature |
|------------|-------------|
| g) | 8°C |
| h) | -10°C |
| i) | 98.6°C |

These are the readings based on the scale and indicator positions.
