Explanation:
The pressure and the heat makes the kernel jump in the air. And it's appearance changes as the kernel is cooked and turns into a popcorn
Answer:
When popcorn heats up, the moisture inside turns into steam, building up pressure until the hull splits and fluffy white corn bursts out, often as the kernel sails into the air. The pop, slow-motion videos reveal, happens out of sync with the hull's rupture and the corn's launch into the air, eliminating two possible explanations for the noise. That left one remaining cause: The sound comes from the release of water vapor as the kernel opens
The reason why popcorn pops is the water trapped inside its kernel. If the kernel is heated to a high enough temperature, this water will transform into steam. Due to the hard and mostly nonporous shell, the steam has nowhere to go, resulting in a buildup of pressure inside the kernel. Once the pressure gets high enough and the temperature reaches about 180 degrees Celsius (355 degrees Fahrenheit), the kernel hull bursts and the popcorn is turned inside out. The characteristic popcorn consistency and white-yellowish foamy appearance results from the starch inside the popcorn kernel. With high temperatures, the starch gelatinizes and then expands with the rapid burst of the kernel. Once it cools down, the solidified flake we know as popcorn is formed. The characteristic popping sound does not originate from the cracking of the hull as originally thought but results from the vapor release after the kernel has cracked.
