Corn does not pop due to stored energy. There is moisture inside the hard kernel of corn. When heated, the heat changes that to steam, which expands, and blows open the kernel. Heat is transformed to mechanical energy- but the heat energy comes from outside, not inside.

Is there really water in popcorn kernels?

All popcorn contain a small amount of water. When the popcorn gets heated the water inside the popcorn kernel turns to steam. The steam then starts to pressure the kernel shell and soon bursts making the kernel inside out, and the soft stuff inside the kernel puffs.


What is in popcorn that makes it pop?

Believe it or not, most hard popcorn kernels have tiny bits of water inside. When these kernels are heated, the water gradually expands and turns into steam. At a certain point, the increasing steam can no longer be contained inside each kernel and explodes through the hard coating, causing a pop. The steam also cooks the starchy material inside kernels, turning it into the fluffy stuff we know as popcorn. Why don't some kernels pop? Such duds probably don't have enough water inside to pop them. From the Kid Wiki Answers


Do different brands of popcorn leave different amounts of unpopped kernels?

Yes, different brands of popcorn may leave different amounts of unpopped kernels due to variations in the type of kernels used, the level of moisture content, and the size and shape of the kernels. Factors such as popping method, storage conditions, and individual kernels' quality can also influence the amount of unpopped kernels.


How Is Popcorn Thermal Energy?

When popcorn kernels are heated, the thermal energy causes the moisture inside the kernel to turn into steam, building up pressure until the kernel bursts open. The transfer of thermal energy in this process results in the popcorn expanding and becoming light and fluffy.


How do you know if popcorn kernels have expired?

You could try popping it. Usually you can tell very quickly, because if the kernels are too old, they won't pop very well. For microwave popcorn, the kernels will remain at the bottom of the bag. Popcorn has a shelf life of approximately two years. After this, it loses moisture and can become stale. It can also expire if the kernels are not stored properly. Popcorn dries out. The tiny bit of moisture inside the kernel is what causes it to pop. Without the moisture, the kernel remains.


How do popcorn kernels grow and develop into the fluffy snack we enjoy?

Popcorn kernels grow on corn plants and are harvested when they are mature. When heated, the moisture inside the kernel turns into steam, causing the kernel to explode and puff up into the fluffy snack we enjoy.


What batch of popcorn kernels would produce more popcorn a batch of kernels soaked in water or a somewhat dried out batch?

I wouldn't advise soaking your popcorn. Popcorn "pops" because 1) there's water INSIDE the kernel and 2) there's a hard shell to hold the water in. Together, these make it possible to build up STEAM inside the kernel until it bursts the shell, effectively turning the kernel inside-out, puffing it up in the process.
