A popcorn kernel pops when it reaches an internal temperature of about 180°C (356°F). At this temperature, the moisture inside the kernel turns into steam, creating pressure until the outer shell bursts, causing the kernel to expand and "pop." This rapid expansion can result in a temperature increase of several hundred degrees in a fraction of a second, transforming the starchy interior into the fluffy popcorn we enjoy.

How does the heat make kernals pop?
Inside each kernel of pop corn is a minute amount of moisture (water), when the kernel gets really hot, the moisture tries to expand into steam and the tight skin of the kernel pops open, spreading the contents.
If you poke a hole through a popcorn kernel will it pop more quickly?
No, you'll ruin the kernel and it won't pop.
Does popcorn pop or unfold?
It explodes! Heat causes the moisture in the kernel to turn to steam, when the pressure builds up and shatters the hull with a pop. The endosperm then solidifies and cools.
Does time affect how many kernels pop in popcorn?
Not time itself, but when time and heat work together, yes. As increasing heat builds up inside the kernel, the steam pressure causes the kernel to explode, or pop, and at the same time cooks the fluffy starch that has given up its water. Longer heating times will still not pop all the popcorn, because some kernels will leak out their steam without breaking open the kernel. Heating these will only cause them to burn up.
What ingredient makes microwave popcorn pop?
The popcorn kernels all contain a drop of water that turns to steam when it is heated. The steam expands the kernel until it pops.
Why does pop corn pop in a fridge?
freezes the moisture inside the kernel
Does soaking popcorn in water make it pop bigger?
No, because too much water in a popcorn kernel will lead to a very weak, if any, pop. The more water in the kernel means you need to heat it longer. If there is too much water in the kernel, the water will never get hot enough to pop.
What do you heat to get a piece of popcorn?
kernel
What does the energy stored in the kernels of corn change into when the energy as the kernels move inside the popcorn popper?
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.
How does jiffy pop heat the popcorn?
The hot air inside the popper heats up moisture inside the kernel of popcorn and it explodes, creating popcorn.
Why do corn kernels pop?
Steam pressure builds in the interior of the kernel until a breaking point occurs in the kernel's shell. Because so much pressure has built up, the interior explodes through the shell and is instantly filled with air, thus its puffiness. The trick is to find the right thickness of the shell, humidity, heat, etc to allow for the largest popped corn.
Why does Popcorn pop when heated sufficiently?
The gas laws are a set of laws that describe the relationship between gases' temperature, pressure, and volume. These laws can be used to explain how an increase in temperature increases the pressure inside of the unpopped kernel. This increase in pressure also generates steam. The steam then explodes out of the outer shell of the kernel. As the pressure fades, the volume expands causing any air bubbles in the popcorn to grow and the kernel to "pop".
