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 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.

What causes popcorn to pop when heated?

As popcorn is heated, the water content inside the hull of the kernel converts to steam, which tries to expand. This presser from the expanding steam ruptures the hull of the kernel.

The change in a popcorn kernel to popcorn changes a liquid to what state of matter?
