The diagram above illustrates the mercury-in-glass thermometer used for determining the temperature of a room. Use the data on it to determine the room temperature.
3.3°C
7.0°C
13°C
30.0°C
Correct answer is D
Let the room temperature be X.
We have, \(\frac{3-0}{10-0} = \frac{X-0}{100-0}\)
\(\frac{3}{10} = \frac{X}{100}\)
\(X = \frac{3 \times 100}{10}\)
= 30°C
