1.	A thin brass sheet at 10∘C and a thin steel sheet at 20∘C have same surface area. The common temperature at which both would have the same area is :Coefficient of areal expension for brass and steel are 10×10−6∘C−1 and 20×10−6∘C−1 respectively.
Answer» A thin brass sheet at $10^{\circ} C$ and a thin steel sheet at $20^{\circ} C$ have same surface area. The common temperature at which both would have the same area is : Coefficient of areal expension for brass and steel are ${10 \times 10^{- 6}}^{\circ} C^{- 1}$ and ${20 \times 10^{- 6}}^{\circ} C^{- 1}$ respectively.
