Do hollow and solid bodies made of the same material have the same expansion when heated even when they have the same external dimension? Posted by spertcy on Apr 25, 2008. |

No. The hollow area will not expand at the same rate as the other material. For instance, if it were an air pocket, the expansion will be huge when heat is applied. At the same time, if a gas fills the hollow area, it will expand according to it atomic weight and properties. Posted by amy-lepore on Apr 25, 2008. |
