Question

reading thermometers
what temperature is indicated on each of these thermometers? unit is °c
a) 68°c b) -3°c c) 11°c d) -1°c e)
f)
h)
i)

Explanation:

Step1: Identify scale intervals

For each thermometer, determine the value of each small - scale division.

Step2: Locate the mercury level

Find where the top of the mercury column is on the scale.

Step3: Read the temperature

a) The mercury is between 60 and 70, and since each small - scale division is 1°C, and it is 8 divisions above 60. So the temperature is 68°C.
b) The mercury is between - 5 and 0, 2 divisions below 0. So the temperature is - 2°C.
c) The mercury is between 10 and 15, 1 division above 10. So the temperature is 11°C.
d) The mercury is between - 5 and 0, 4 divisions below 0. So the temperature is - 4°C.
e) The mercury is at 28°C.
f) The mercury is between 10 and 20, 6 divisions above 10. So the temperature is 16°C.
g) The mercury is between 0 and 10, 8 divisions above 0. So the temperature is 8°C.
h) The mercury is between - 10 and - 15, 3 divisions below - 10. So the temperature is - 13°C.
i) The mercury is between 98 and 99, 1 division above 98. So the temperature is 98.5°C.

Answer:

a) 68°C
b) - 2°C
c) 11°C
d) - 4°C
e) 28°C
f) 16°C
g) 8°C
h) - 13°C
i) 98.5°C
