The problem provides images of thermometers showing air temperatures at different times of the day. We need to determine the temperatures from the thermometers and fill in the table. We are also given that 5:00 was the lowest temperature and 11:00 was the highest.
| Time of observation | 5:00 | 11:00 | 17:00 |
|---|---|---|---|
| Air temperature, °C | -10 | 20 | -10 |
Final Answer: The table is filled with the observed temperatures: -10°C at 5:00, 20°C at 11:00, and -10°C at 17:00.
