Certain materials expand when they are heated.   If a spherical 
object measuring one foot in diameter having an inter cavity of 
one inch were to become heated, depending on the material used 
of course, will the inner cavity get bigger or smaller?  If the 
cavity gets smaller than how much pressure does it produce as it 
pushes its way inward?  Where can I find a list that shows the 
rate of expansion on a materials as it becomes heated and a list 
that shows the pressure produced as the material expands?
