(A purist would say that even when it's off, it still radiates heat more or less as a blackbody. 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. Conduction is the transfer of heat through direct contact, like when you touch a hot stove. Radiation therapy employs extremely high-powered x-rays, particles, or radioactive seeds to destroy cancer cells. The system is equipped with a fan, heating element, and vent.

Because corn is wind-pollinated, it pays to plant in blocks of four rows, following the sowing instructions for depth and spacing. Once they reach the right temperature in the pot and the vapor pressure inside the kernels gets high enough they burst open and jump into the air producing a nice popcorn puff. That's how microwave popcorn works. Now, take the pile of cracked popcorn kernels (that you cut with a knife) and add them to the pot. Even the right strain of corn won't pop unless its moisture content has a moisture content around 14 to 15%. The characteristic popping sound does not originate from the cracking of the hull as originally thought but results from the vapor release after the kernel has cracked. With the last popcorn batch that you preheated in the oven you should have seen a similar outcome.
