When a metal ring is heated

A metal sheet with a circular hole is heated. The hole will

When a metal rod is heated it expands because

A metal sheet with a cricular hole in heated. The hole

When solid is heated , its length changes according to the relation l=l_0(1+alphaDeltaT) , where l is the final length , l_0 is the initial length , DeltaT is the change in temperature , and alpha is the coefficient of linear is called super - facial expansion. the area changes according to the relation A=A_0(1+betaDeltaT) , where A is the tinal area , A_0 is the initial area, and beta is the coefficient of areal expansion. A metal disc having a circular hole at its center is heated . If the metal expands on heating , the diameter of the hole
