1. 15
The labels go up by 10 degrees with 10 spaces between them, so each mark is 1 degree.
The liquid stops 5 marks above 10: 10 + 5 = 15.
The thermometer shows 15 °C.
2. 24
The labels go up by 10 degrees with 10 spaces between them, so each mark is 1 degree.
The liquid stops 4 marks above 20: 20 + 4 = 24.
The thermometer shows 24 °C.
3. 17
The labels go up by 10 degrees with 10 spaces between them, so each mark is 1 degree.
The liquid stops 7 marks above 10: 10 + 7 = 17.
The thermometer shows 17 °C.
4. 37
The labels go up by 10 degrees with 10 spaces between them, so each mark is 1 degree.
The liquid stops 7 marks above 30: 30 + 7 = 37.
The thermometer shows 37 °C.
5. 18
The labels go up by 10 degrees with 10 spaces between them, so each mark is 1 degree.
The liquid stops 8 marks above 10: 10 + 8 = 18.
The thermometer shows 18 °C.
