when a copper sphere is heated, maximum percentage change will be observed in (1) radius (2) area (3) volume (4) none of these

 Answer: (3) volume

Explanation

Change in radius =rΔr=X

Change in area =Δ(4πr2/(4πr2)

=Δr2/r2

= 2Δr/r

=2X

Change in Volume =Δ(4/3πr3/(4/3πr3)

=Δr3/r3

= 3Δr/r

= 3X

Thus change in volume is maximum.
