This causes the water inside the kernels to expand and the kernels to pop. Physics Introduction Researchers have found out that people who ate popcorn regularly increased their daily fibre intake by 22%. You can also evaluate popcorn quality by measuring kernel expansion, which means how big the popped popcorn flakes get. Microwaves cause the water molecules in the popcorn kernels to vibrate in response to the microwaves, resulting in heat. The flavor of radiation-popped popcorn is also different from other types of popcorn. The rate of heat transfer per unit area per unit temperature is defined as the heat transfer coefficient (h). Hot air popping is the most efficient method of the three, as it uses hot air to cook the kernels evenly and quickly. Extra: Test to find the ideal popcorn popping temperature.

There are many methods of cooking popcorn, but using radiation is one of the most effective. Once the pressure gets high enough and the temperature reaches about 180 degrees Celsius (355 degrees Fahrenheit), the kernel hull bursts and the popcorn is turned inside out. A popped popcorn package should have the same weight as one that has been popped (you should measure the weight after popping the package to determine the mass after popping).
