A bimetalic strip is made of two strips A and B, having co-efficeint of linear expansion as alpha_(A) and alpha_(B) . If alpha_(A) gt alpha_(B) which of the following describes the behavior fo the metallic strip when heated?

A : The bond angle of NH_3 is greater than BiH_(3) . R : 'Bi' is metal while N is non - metal .

Statement-1: Pb, Sn and Bi are purified by liquation. Statement-2: Impurities have lower meltin point than metal.

A bimetallic strip is formed out of two identical strips one of copper and the other of brass. The co-efficients of linear expansion of the two metals are alpha_(C) and alpha_(B) . On heating, the the strip bends to form an are of radius of curvature R . Then R is

A bimetallic strip is formed out of two identical strips one of copper and the other of brass. The coefficients of linear expansion of the strip goes up by DeltaT and the strip bends to from an arc of radius of curvature R. Then R is.

BI_(3) is an ionic compound.
