Is making popcorn a physical or a chemical change?

Answer 1

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.

Answer 2

Popping Popcorn is both a Physical and Chemical change because the starch in the kernal explodes making it a physical change... Also a chemical change because we can't put it back in it's original state... Hope this Helps... X-)

Answer 3

Melting popcorn is a physical change. Because once it is melted you can allow it to harden again by leaving it out or putting it back in the fridge. If it was a chemical change you would not be able to re-solidify it.
It is a physical change. You are simply changing the state of the material, as opposed to changing the compound.

Answer 4

The chemicals existing in the corn kernel have the same chemical composition after popping as before. The change in shape is due to physical reasons.

Another has said: "Is the cooking of popcorn a physical or chemical change?" Secondly the cooking or making of popcorn is a chemical change. This is because you start out with seeds and then when you add oil or sometimes butter and expose the butter or oil and corn seeds to heat the substances will combine and with the heat create popcorn. Therefore the cooking or making of popcorn is a chemical change or chemical reaction.

Answer 5

Chemical change. Most of the time when heat is used a chemical change has taken place. Because it can not return to its original state.

Answer 6

No, it is a physical change. I'm not sure why, but you can search it on Google. It says chemical change. :)

Answer 7

Many people think so, but it doesn't create a new substance from two or more chemicals. So, popping popcorn is not a chemical property, but a physical one.

Answer 8

Chemical.
