A droplet of water. That's why it pops when it gets heated. The water boils, turns into steam, increases pressure inside the kernel, until it can't take it anymore and it pops! Also, popcorn dries out, and that is often the cause of the kernels not popping. So, if you can, you should store your popcorn in an airtight container and put a small amount of water inside and shake it up. The kernels will absorb the water and you'll have more success with popping.
pericarp is the name of the outer covering of a kernal of corn, if that is what you are asking.
Wheat kernels are made up of three components: endosperm, bran, and germ.
On the outside is the husk, then the grain itself an at the center is what's called the germ.
endosperm germ or embryo pericarp
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.
The hot air inside the popper heats up moisture inside the kernel of popcorn and it explodes, creating popcorn.
The air and water vapor inside the kernel is expanding.
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.
The compound known chemically as "H20" - water. There is a tiny drop of water at the heart of every corn kernel. When heated, it turns to steam, and turns the corn kernel "inside-out" - that's popcorn.
Inside each kernel of pop corn there is a very small amount of water. When the kernels get hot the water expanded as steam and explodes the kernel.
Yes. As the temperature increases, the pressure inside the kernel increases, causing the popcorn to pop
Popcorn is formed when a kernel gets heated. The kernel explodes and then turns inside-out.

The average percent of water in popcorn kernels is around 13-14%.
It is called "a piece ( or kernel) of popcorn," or more properly if less often, " a popped kernel," or "a popped corn."
