A platinum resistance thermometer records 3.0(Omega) at 0oC and 8.0(Omega) at 100oC. If it records 6.0(Omega) in a certain environment, The temperature of the medium is
-
A.
80oC -
B.
60oC -
C.
50oC -
D.
30oC
Correct Answer: Option B
Explanation
8(Omega)…..100oC
6(Omega)…..(theta)oC
3(Omega)…..0oC
(frac{6 – 3}{8 – 3}) = (frac{theta – 0}{100 – 0})
therefore, (theta) = 60oC
