HomePhysics when a copper sphere is heated, maximum percentage change will be observed in (1) radius (2) area (3) volume (4) none of these byBalkishan Agrawal -July 13, 2022 0 Answer: (3) volumeExplanationChange in radius =rΔr=XChange in area =Δ(4πr2/(4πr2)=Δr2/r2= 2Δr/r=2XChange in Volume =Δ(4/3πr3/(4/3πr3)=Δr3/r3= 3Δr/r= 3XThus change in volume is maximum.
