A student records the initial length l, change in temperature `Delta T` and change in length `Delta T` of a rod as follows
`{:("S.No.","l(m)",Delta T(.^(@)C),Delta l(m)),(1.,2,10,4xx 10^(-4)),(2.,1,10,4 xx 10^(-4)),(3.,2,20,2 xx 10^(-4)),(4.,3,10,6 xx 10^(-4)):}`
If the first observation is correct, what can you say about observation 2, 3 and 4.

To analyze the observations made by the student regarding the thermal expansion of a rod, we will use the formula for linear expansion: \[ \Delta L = \alpha L \Delta T \] where: - \(\Delta L\) = change in length ...
