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?
