. There are two spheres of same material and radius. One is solid and other is hollow. If they are heated to same temperature the expansion of

1. solid sphere is more

2. hollow sphere is more

3. solid and hollow sphere are equal

4. solid is outward while hollow is inward

Best Answer

Ans: 3

ΔV = VγΔT

Or ΔV ∝ ΔT

Q Material and temperature difference are same for both spheres. So expansion are equal.
