You should have easily seen the difference in popcorn size and volume once you put the kernels into the glasses at the end of the activity. Heat. At the same time in the popcorn endosperm, the starch granules expand adiabatically [which means heat is reduced through a change in air pressure caused by volume expansion] and form a spongy flake of various shapes. When heat from the core of a white-hot body is transferred to a brittle lithosphere, it is convection in the mantle. An Illustrated Expedition of North America, Popcorn: Ingrained in America's Agricultural History. The best popcorn, like Moms, is made in a large heavy pot with oil on the stove.
