Explanation:
Let’s read the bar graph carefully. The vertical axis (Y-axis) shows temperature in degrees Celsius, and the horizontal axis (X-axis) shows times on Monday: 6AM, 10AM, 2PM, 6PM, and 10PM.
We need to find the height of each bar — that tells us the temperature at that time.
1.
What was the air temperature at 10PM?
Look at the bar for “10PM”. Its top aligns with the line for
4°C on the Y-axis. So, temperature = 4°C.
2.
What was the air temperature at 2PM?
The bar for “2PM” reaches up to
8°C. So, temperature = 8°C.
3.
Did the temperature increase or decrease between 6AM and 10AM?
- At 6AM, the bar reaches
12°C.
- At 10AM, the bar reaches
16°C.
Since 16 > 12, the temperature
increased.
4.
Was the temperature higher at 6PM or 10AM?
- 6PM bar =
20°C
- 10AM bar =
16°C
20 > 16, so temperature was higher at
6PM.
5.
At what time was the temperature at the lowest?
Compare all bar heights:
- 6AM: 12°C
- 10AM: 16°C
- 2PM: 8°C
- 6PM: 20°C
- 10PM: 4°C
The smallest value is
4°C, which occurs at
10PM.
Let me double-check each value against the grid:
- Y-axis has marks every 4 units: 0, 4, 8, 12, 16, 20, 24, 28, 32, 36.
- 6AM bar ends at 12 → correct.
- 10AM bar ends at 16 → correct.
- 2PM bar ends at 8 → correct.
- 6PM bar ends at 20 → correct.
- 10PM bar ends at 4 → correct.
All values match.
Final Answer:
4°C
8°C
increase
6PM
10PM
