Question

Find alfa if resistance of electrolytes at 0 and 90 degrees are 34.5 and 13.4ohm​

Answer 1

Answer:

-0. 006/°C

Explanation:

R(90)= 13.4 ohm

R(0)=34.5ohm

temperature (t) =90°C

therefore, R(90)=R(0) [1+alpha*t ]

or, 0.38 - 1 = 90*alpha

or, -0.611 = 90*alpha

or, alpha= -0.006/°C [ANS.]
