1.	A hole is drilled in a copper sheet. The diameter of the hole is4.24 " cm at " 27.0 ^(@) C. What is the change in the diameter of the hole when the sheet is heated to227^(@) C ? Coefficient of Imear expansion of copper = 1.70 xx 10^(-5) K^(-1).
Answer» Solution :The diameter INCREASES by an amount ` = 1.44 xx 10^(-2) CM`.
