Question

16. Two spheres of the same size are made of the same metal. A sphere is hollow
And the other one is solid. They are heated to the same temperature as a result
(a) Both the spheres will spread evenly
(b) Hollow sphere will spread more than solid sphere
(c) Solid sphere will spread more than hollow sphere
(d) Both the spheres will remain in the previous position


plz ans with explanation​

Answer 1

Here, we know that both the body is made up of same material, hence its orientation will do not affect it's expansion.

Hence,

V

solid

ΔV

solid

=

V

hollow

ΔV

hollow

=γΔT

Therefore we can say both sphere will expand same, because material used for making both of them are same.
