# When a copper sphere is heated maximum percentage change will be observed in

$(a)\;radius \quad (b)\;area\quad (c)\;volume \quad (d)\;none$

$\Large\frac{\Delta s}{s}$$=2 \Large\frac{\Delta r}{r} \Large\frac{\Delta v}{v}$$=3 \Large\frac{\Delta r}{r}$
Hence the percentage change in volume will be maximum
Hence c is the correct answer.
