Two spheres of the same size are made of...

Two spheres of the same size are made of the same metal, but one is hollow and the other is solid. They are heated to the same temperature. Then,

A

The solid sphere expands more

B

The hollow sphere expands more

C

Expansion is same for both

D

Nothing can be said about their relative expansion if their masses are not given

Text Solution

Verified by Experts

The correct Answer is:
C
As `Delta V = gamma V Delta T`
Here V, `gamma` and `Delta T` are same for both solid and hollow spheres.
So the expansion for both spheres will be equal.
