Q : 16 The length (in centimetre) of a copper rod is a linear function of its Celsius temperature . In an experiment, if when and when , express in terms of .
It is given that
If then
and If then
Now, if assume C along x-axis and L along y-axis
Then, we will get coordinates of two points (20 , 124.942) and (110 , 125.134)
Now, the relation between C and L is given by equation
Which is the required relation
