The small bit of water inside the kernel turns to steam, which rapidly expands, causing the material to burst into the popped kernel. So the expansion and bursting is physical. But the heat does perform some chemical changes as well.
Two physical properties of a bag of microwave popcorn before popping are its mass and volume, which remain constant before and after popping. Two chemical properties that change after popping are the composition of the kernels, which undergo a chemical reaction to turn into fluffy popcorn, and the release of aroma compounds due to the Maillard reaction during popping.
yeah, because you can't make the popcorn seeds again.
When popcorn is burned, it undergoes a chemical change because the heat causes a chemical reaction that changes the chemical composition of the popcorn. This results in the formation of new compounds, such as carbon, that are different from the original chemical composition of the popcorn.
It is a physical change.Density is not a chemical property. Instead, it is a physical property.
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.

The act of popcorn popping is a physical rather than chemical change. Air within the popcorn seed is heated, causing it to build up to higher pressure than the air outside. As a result of this, the air is explosively released to the area of lower pressure, in effect popping the popcorn.

Melting butter for popcorn is a physical change because the butter undergoes a change in state from solid to liquid without any chemical composition changes.
Chemical - a physical change can be reversed , e.g Freezing water, melting chocolate. But something like popping corn is ireversible like baking a cake or boiling a egg. Hope this helps.
It would be a chemical change because you can't reverse your action of popping the kernels , which can define a chemical change.
Once you make it....you won't get that small seed back where as water can Evaporate and then Condense again, which is a Physical Change...so that is why popcorn is a Chemical Change
Popping a balloon is a physical change because the balloon retains its original chemical composition even after it has been popped. The change is reversible, as the pieces of the popped balloon can be put back together and reinflated.
