moisture which makes the kernels turn into popcorn

Water expands when frozen, so it pressurizes the kernels. This makes them easier to 'pop' when the water boils and tries to escape all at once.
Different bags mean different ages and storage places. They could of been made with different things and older things. All popcorn bags are different might have less kernels or less unpopped kernels when u cook it. I am doing a science fair project and I'm doing it on, "Does the different brands of popcorn affect the total of unpopped kernels?" I have a lot of info that you can see above. You think there is no a lot of info but go to Google and type in, "does different types of popcorn affect the total of unpopped kernels and look. One thing that makes a difference is amount of popcorn in the bag, how much time you put it in for, and the most important is INGREDIENTS. This girl did something like this and she said palm oil makes a difference. The smallest things make the biggest differences.
As long as you use regular popcorn kernels with nothing added to them, it really makes no difference in the taste of the popcorn if you pop it in the microwave or in a popcorn maker. However, if you are using the packets of microwave popcorn that have added flavorings and fat, I would say that plain popcorn tastes better. If you want to make popcorn conveniently but without additives, I would recommend putting about a quarter of a cup of popcorn kernels in a regular brown paper bag along with about a teaspoon of vegetable oil and using that to pop the popcorn in the microwave instead of the microwave popcorn bags from the grocery store. You simply add the kernels and oil in the bag, seal it up tightly, then microwave for two to three minutes, until you hear the kernels stop popping. This is significantly healthier, cheaper, and better-tasting than store-bought popcorn.
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
The microwave agitates the water inside of all of the corn kernels. The water turns to steam which expands and builds increasing pressure inside of the kernels until they pop (explode).
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.

The air popcorn maker that make the best tasting popcorn is the 'Presto PopLite Hot Air Corn Popper' according to most of the reviews online, most reviewers say that it makes popcorn with the perfect crunchiness with very little non popped kernels and none burnt.
Yes temperature does affect how popcorn pops. It the temperature is too low, not very many kernels will heat up enough to explode. If the temperature is too hot, you will burn the kernels that explode first. Using a stir type hot air popper will eliminate some of these issues.
