Statement - 1 : The expanded length l of a rod of original length l₀ is not correctly given by (assuming α to be constant with T) l = l₀ (1 + α∆T),
if α∆T is large.
Statement - 2: It is given by l = l₀ e^α∆^T, which cannot be treated as being approximately equal to l = l₀ (1 + α∆T) for large values of ∆T.
