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.
99% of making popcorn is a physical change -- you're flashing liquid water in the kernel into steam; not chemical in that you're changing the shaps of the corn but not the composition. The exceptions are that a tiny amount of protein may be denatured, and if you burn it you're into chem change city.
its a chemical change because its popping and its in the heat
Physical change, mostly. The starch isn't converted into anything else but the heat does change the chemical structure somewhat.
No, because i think its a physical change and thats because nothing is being addded or melting just a form of changing the cornballs. The way it appears is different.
It's a physical change.. The popped corn is still corn - the heat from the pan simply made the kernels expand so they burst out of their seed cases.
Physics, not chemistry. PV=nRT
A physical change
Physical... chemically, it's still the same substance,
Physical change of the paint, not the door.
It is Chemical Property that can Neutrilize a Base

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.
Some chemical reactions occur during the preparation of popcorn.
Physical properties of a bag of microwaveable popcorn are the mass of it, the color of it, the size of it, and the weight of it. Two chemical properties of a bag of microwavable popcorn are it changed from seeds to popcorn and it popped.
The seeds get heated which puts pressure on the seeds and makes the popcorn
no popping popcorn is
YES

It is a physical change.
yeah, because you can't make the popcorn seeds again.
it is a chemical change
