And how does this differ from what occurs during an atomic
explosion. The Chicken Soup scenario is an externally imposed
EXPANSION caused by the insertion of heat particles. The
compression or expansion in such as case is regulated by the
container. In the case of your Chicken Soup, the tin can was not
designed to withstand extreme pressure, in fact has seams that
come apart as easily as they were put together. Translating this
scenario to a meteor, which heats FROM THE OUTSIDE IN, would not
find the meteor interior getting hot but would find the exterior
melting, thus allowing expansion of any interior warming. Your
meteor would burn on the outside, melt on the outside, but would
not explode.
