Question on: JAMB Physics - 1997
The length of mercury thread when it is at 0oC, 100oC and at an unknown temperature (\theta) is 25mm, 225mm and 175mm respectively. The value of (\theta) is
A
85.0oC
B
80.0oC
C
75.0oC
D
70.0oC
Ask EduPadi AI for a detailed answer
Correct Option: C
(\frac{\theta\ - 0}{100 - 0}) = (\frac{175 - 25}{225-25})
(\theta) = 75.0oC
