a resistance of platinum wire is 2 ohm at zero degree and 2.5 at 100 degree.then at what temperature its resistance would be 2.3 ohm.

3 answers

is the change linear? If so, then

since 2.3 is 3/5 of the way from 2.0 to 2.5,

the temperature would be 3/5 of the way from 0 to 100 degrees.

Please i need more explanation
