Question on: JAMB Physics - 2013
Calculate the length which corresponds to a temperature of 20oC if the ice and steam points of an unguarded thermometer are 400 mm apart
A
20mm
B
30mm
C
60mm
D
80mm
Ask EduPadi AI for a detailed answer
Correct Option: D
At 100oC = 400
Therefore,
At 20oC = \(\frac{400}{100} \times \frac{20}{1}\) = 80
Therefore,
At 20oC = \(\frac{400}{100} \times \frac{20}{1}\) = 80
