Physicists Reveal the Secrets of Perfect Popcorn, from The Washington Post Due to the fact that popcorn is not cooked using hot air, the microwave does not use hot air to cook it. To distribute heat, oil is used in the wet method, resulting in a more even popping sensation. The hot air circulates evenly, so every kernel comes out perfectly popped. The popcorn machine converts electrical energy to thermal energy, which causes the popcorn to sizzle. The heat from the stovetop transfers to the pan, and then the hot air in the pan transfers to the popcorn kernels. Continue reading with a Scientific American subscription. Hot air popping is the most efficient method of the three, as it uses hot air to cook the kernels evenly and quickly. The air in the room and the food in the food can be heated in microwave ovens. Virot told LiveScience that the unpopped kernels likely have defective hulls, which prevent high pressures from building inside. One fluid stream can cool and another can heat due to forced convection. When the popcorn kernels are placed inside the popper, a heating element heated the air, and then the fan directed the heated air onto the popcorn.
