Two spheres of the same radius are made from the same material. One is hollow and the other is solid. If they are heated together from 20 ° C to 100 ° C .

Question

Two spheres of the same radius are made from the same material. One is hollow and the other is solid. If they are heated together from 20 ° C to 100 ° C . (A) both will expand equally (B) hollow sphere will expand more (C) solid sphere will expand more (D) the relative expansion of solid and hollow sphere depends on the material of sphere

Tardigrade Admin · Accepted Answer

both will expand equally as thermal expansion depends on size, material and temperature, which are same in all the two.

Q. Two spheres of the same radius are made from the same material. One is hollow and the other is solid. If they are heated together from 20∘C to 100∘C .

both will expand equally

hollow sphere will expand more

solid sphere will expand more

the relative expansion of solid and hollow sphere depends on the material of sphere

both will expand equally as thermal expansion depends on size, material and temperature, which are same in all the two.
