1.	The coefficient of linear expansion of brass and steel are α1 and α2. If we take a brass rod of length l1 and steel rod of length l2 at 0∘C, their difference in length (l2−l1)will remain the same at a temperature if
Answer» The coefficient of linear expansion of brass and steel are $α_{1}$ and $α_{2}$ . If we take a brass rod of length $l_{1}$ and steel rod of length $l_{2} a t 0^{\circ} C,$ their difference in length $(l_{2} - l_{1})$ will remain the same at a temperature if
